Wireless Bluetooth Ergonomic Trackball Mouse with RGB Backlight

The ProtoArc EM03 Ergonomic Wireless/Bluetooth Trackball Mouse, delivered in secure packaging with a USB-A to USB-C cable and a user manual, was chosen for its anticipated comfort for use with my PC and laptop. Its sizable design features a left button under the thumb and a right button for the middle finger, complemented by a scroll wheel and back/forward buttons, with the trackball situated on top for the index finger. Offering both 2.4GHz dongle and Bluetooth connectivity, I found that it can also be used while charging via a wired connection. The standout feature of this mouse is the stationary hand position, utilizing the trackball for movement. Initially, this felt quite alien compared to a traditional mouse, but I quickly adapted to its comfortable and quiet operation. A surprising benefit was the Bluetooth functionality. It's not just for my PC; I also connected it to my tablet, which I use as a secondary screen. The mouse can connect to up to three devices, a handy feature.

This ergonomic trackball mouse is among the better ones I've used and is reasonably priced for its quality. While I generally prefer traditional mice, trackballs are handy when desk space is limited. It connects seamlessly via built-in Bluetooth or the 2.4G USB dongle stored underneath the trackball. I've experienced no connection issues using either method on my laptop and tablet. The battery charges in a couple of hours and lasts well. The trackball's smoothness, combined with just the right amount of friction, offers excellent control. The scroll wheel, positioned on the left, is responsive and conveniently located for thumb use. The mouse also features nice tactile buttons and multiple DPI settings, ranging from 200 to 1600, along with a few subtle RGB lighting options. Overall, it's a well-balanced choice between quality and price for a trackball mouse.

Having dealt with carpal tunnel and other hand issues as an artist, I've been curious about trackball mice for some time. This ergonomic trackball mouse has been a game-changer for me, much easier to adapt to than I expected. The ball glides smoothly, though it occasionally sticks, which is easily remedied by cleaning it. The ergonomic design is exceptional, initially surprising given the distance between the left and right click buttons, but ultimately proving to be very comfortable. The shape supports my hand well, enhancing my internet browsing experience. While I haven't used it for gaming, it's been great for productivity and 3D modeling, offering more control than a joystick. It's been a highly satisfying experience overall, and I strongly recommend it for anyone interested in trying a trackball mouse.

This ergonomic trackball mouse is easy to install and impressively large, with easily accessible control buttons. The colored light effect is a nice addition, though it seems more suited for gamers. The size allows for less hand movement, and the mouse is quick to respond and reliable. The design is visually appealing, and I appreciate that the mouse is rechargeable, eliminating the need for batteries. While there's a bit of a learning curve for those used to traditional mice, there are no major complaints about its performance.

This ergonomic trackball mouse came as quite a surprise. As a first-time trackball user, I was initially unsure about its performance compared to a regular mouse. There's definitely an adjustment period, but it quickly becomes more comfortable to use than a standard mouse. Its design seems tailored to fit the hand naturally. It's heavier than my previous, smaller mouse, but that's a minor adjustment. Setting up and operating the device is straightforward, and it functions smoothly. While it's not the cheapest mouse at around £50, its quality justifies the price. For those looking for a trackball mouse in this price range, I believe this is a good option.

If you're aware of the type of mouse you're purchasing, then this ergonomic trackball mouse is fantastic. Its design is unique and works well, offering a comfortable ergonomic experience. You only need three fingers (thumb, index, and middle) to operate it, leaving your palm and arms relaxed. Another feature I appreciate is the lack of a loud clicking sound. The mouse is quite heavy, but it's suitable given its atypical operation. It takes some time to get used to, but once you do, it's incredibly easy and relaxing to use. The trackball feature, operated by the index finger, allows more space for relaxed cursor movement. This mouse is ideal for office use, not gaming, as it lacks programmability and has fewer buttons compared to gaming mice. I consider it a 'lazy mouse' due to its stress-free operation.

The ergonomic trackball mouse boasts top-notch accuracy and comfort, even if it's a bit large. The light effect is a nice touch, not disturbing at all, even when it lights up the area next to the table. The battery life is excellent. Despite its price, the quality is worth it, and I would definitely purchase it again. The high-quality ball is easy to remove for cleaning, eliminating the hassle of sliding around on the table. It's also great for use on a sofa or other surfaces. Highly recommended!

I was pleasantly surprised to find that the EM03 is almost identical to the Microsoft Explorer, which I used for over a decade before it broke. The EM03 offers more in terms of technical and visual features, making it the perfect replacement for the discontinued Explorer.

Rediscovering the joy of using a trackball mouse, I found this model to be a worthy successor to my beloved MS Trackball Explorer. The keys are soft to the touch with a clear actuation point, making the operation very ergonomic. Its design allows for the use of one or more fingers in various positions, enhancing comfort. Unfortunately, it's designed only for right-hand use. A notable drawback is the absence of a dedicated trackball driver. However, the X-Mouse Button Control software provides a workaround, offering free key programming. It's available in both an installation and a portable version. My rating would be a full five stars if it included a driver, but it still earns a solid four.

Purchasing this trackball mouse as a replacement for my old "Trackman Marble" has left me completely satisfied. The precision control of the cursor with the trackball is excellent, and the ergonomics are commendable. Unlike some alternatives, it operates smoothly without any scratching. The setup was straightforward, and surprisingly, the forward and backward buttons work on macOS, contrary to the product description. The quiet and smooth operation of both the ball and keys is a pleasant aspect. While saving a cable isn't crucial for me, it's a nice bonus. For now, I highly recommend this purchase.

This well-crafted, ergonomically designed rollerball mouse has been a great find. Its compact USB Bluetooth stick, easy to locate beneath the mouse, makes connecting via Bluetooth straightforward. The instruction manual is clear, helping me understand the functions of each button. The mouse fits nicely in my medium-sized palm, and the rollerball operates smoothly. The orange scroll wheel is visible at a glance, and the mouse's matte surface provides a comfortable grip. The DPI selector on the rear is a convenient feature, allowing adjustment based on my activity.

I'm very impressed with this ergonomic trackball mouse. Easy to set up and operate, though it does require a bit of adjustment due to its sensitive ball. The design is especially beneficial for those who experience discomfort or pain using traditional mice. After a wrist injury, this mouse has been a revelation, greatly reducing my end-of-day wrist aches. The build quality is excellent, with seamless operation of buttons, roller, and trackball. It's a significant upgrade from my previous mouse.

My new ergonomic mouse, significantly larger than my previous one, has greatly improved comfort for my hand and wrist. Working from home, I often faced discomfort using standard mice, but this finger-operated trackball mouse has reduced that strain significantly. The larger size also allows my entire hand to rest more comfortably on the mouse. Although it took some time to adjust to the size, the overall experience has been much better.

This ergonomic trackball mouse is of great quality and very easy to set up. Simply unplug the USB dongle from the mouse, connect it to your computer, and you're ready to go. Its appearance is appealing, especially with the calming RGB lighting. The soft-touch feel and layout make it comfortable to use, reducing hand fatigue. It has all the necessary features, making me very content with my purchase.

After long hours in front of the screen, this ergonomic trackball mouse has been a great companion for my hand. No more awkward wrist movements; the finger-operated trackball brings peace to my arm and wrist. It connects easily to multiple devices, and the light effects are a pleasant addition. One needs to be mindful of the power switch to prevent quick battery drain. The quiet clicking contributes to a more focused workspace.

As a first-time user of a trackball mouse, I was skeptical about its functionality compared to a regular mouse. There's a bit of a learning curve, but the comfort it offers is superior. The design feels more natural in the hand, as if it's tailored to work with your hand's shape. It's noticeably heavier than my previous, smaller mouse, but that's a minor adjustment.

This ergonomic trackball mouse is a gem, especially for someone like me who uses multiple laptops. The ease of switching devices with just a button touch is fantastic. The only improvement I'd suggest is relocating the buttons to the top or side instead of underneath. Nonetheless, it remains an excellent piece of equipment.

I really enjoy using this ergonomic trackball mouse. It's surprisingly easy to get accustomed to, and the battery life is commendable, lasting several days before needing a recharge. I find myself wishing I had made this purchase sooner.

This mouse has surpassed my expectations in every way. It's an amazing device that I use for 10-15 hours daily across various computers and laptops. Perfect for my workflow, it allows me to scroll through documents and webpages with ease and high precision.

The ergonomic trackball mouse works quite well overall. However, it's not entirely smooth; occasionally, the ball sticks a bit. This isn't a major issue for me, but for those needing flawless operation for tasks like design work, it could be a point of frustration.

Deciding to try out a trackball, I found this model to be excellent! It can sync with three different computers, is wireless and rechargeable, comfortable to use, and has a terrific side scroll wheel. Overall, it's a great addition to my desktop setup.

This is a very solid trackball with a no-slip base. Its ergonomic contoured shape fits my adult hand well, and the trackball action is very smooth. I haven't connected it to another PC or device, but the support for more than one connection is a great feature.

The ProtoArc Wireless Bluetooth Trackball Mouse, EM03 Ergonomic RGB Rollerball Mouse, has an excellent feel. The hand position is more comfortable, and the trackball feature improves operation as I don't have to move the mouse around. The ability to set up connections with three devices is a nice feature.

I've been a fan of using trackball mice for a few years now, starting with the Deft Pro and then the Huge. This new trackball is comparable right out of the box. Although I've modified my Elecom trackballs and still prefer them, this new one offers excellent value. Interestingly, the ball is the same size as the Deft Pro ball, so they are interchangeable, which is pretty cool.

Working from home, I struggled with using a trackpad all day, which led me to try this ergonomic trackball mouse. It resolved my issues of hand discomfort caused by regular mice. It's comfortable for extended use and doesn't cause any hand pain. I appreciate its wireless connectivity, easy setup, excellent battery life, and well-positioned scroll wheel. I'm really happy with this mouse.

I purchased this trackball as a replacement for an older model that had reached the end of its lifespan, and I'm quite impressed with it. Although I usually prefer a thumb-operated trackball, I've adapted to this forefinger-operated model and it works great.

For those who prefer using a trackball, this one is worth trying. It's responsive, comfortable to use, and even looks good on the desk. It fits my hand well (I wear a size L glove), though it might be less comfortable for those with very small or very large hands. Overall, I find it very comfortable.

I use this trackball for a computer that doesn't have much desk space, as it's a server. It's great to have this trackball instead of a regular mouse, which would require more space. The build quality is good, and it offers the choice of using a USB dongle or Bluetooth, which I really like.

This trackball is incredibly easy to use and extremely ergonomic, making it a pleasure to operate.

In terms of price, this is the best trackball mouse available. The build quality and design are excellent.

For a few years now, it's been challenging to find a good index-operated trackball. It's a relief to finally find one that works well and is reasonably priced.

This trackball is exceptional. The ball tracks very smoothly, and the shape is comfortable in the hand. The ability to pair with two different devices over Bluetooth and a third via the RF dongle offers great connectivity options. The RGB ring around the ball is a stylish addition.

I love this trackball. Among the many I've used, this is the first that fits my hand correctly since the Microsoft Explorer Trackball. Its design allows me to control the cursor with my three middle fingers, which is a huge plus for me.

After using this mouse for about a month, I am very satisfied with its performance. It features an internal battery for wireless use, though I usually keep it connected. The ball movement is smooth and precise. It connects wirelessly via Bluetooth, so no separate dongle is needed. The USB-C connection for charging is convenient, as it matches most newer phone chargers. The mouse fits my hand well and is very comfortable for extended use.

This mouse has been a game-changer for me, especially in my non-ergonomically set up workspace. It significantly helps in reducing my shoulder pain.

This mouse is fantastic, easy to use, and comfortable, preventing hand fatigue. I absolutely love using it.

The variety of connection options is impressive, including two different Bluetooth modes and a wireless USB. For KVM users, the wireless USB is a seamless choice. It plugs into the KVM slot and switches effortlessly, unlike Bluetooth connections which can be problematic. The ergonomic design is excellent, with a ball that rolls smoothly, a comfortable size, and well-placed buttons of the right size.

I absolutely love this mouse! After sustaining a hand injury, I decided to upgrade my mouse, and I'm thrilled with the result. The smooth operation, quiet buttons, and attractive design with cool lighting effects make it a joy to use. I'm very happy with this purchase.

As a longtime user of trackballs, especially the Logitech Marblemouse USB, this trackball stands out as the best I've ever used. Unlike others, it excels in fingertip control rather than thumb-ball control. The rolling action is both excellent and precise. I appreciate that it comes with a built-in 2.4 GHz adapter and also offers Bluetooth connectivity. Additionally, the smooth scrolling feature is a significant upgrade from the Marblemouse. Overall, I am extremely satisfied with this trackball.

The only significant flaw of this mouse is the high sensitivity of the left and right buttons, which can lead to accidental presses.

Although it takes some time to get accustomed to, this trackball is particularly useful for programming tasks.

I've been using Logitech and Kensington trackballs for as long as they've been around. Due to a past thumb injury, I can't use thumb-driven trackballs. Deciding to try this new model, I was not disappointed. It's a bit larger than I expected but has a great ergonomic feel and smooth action. It's just heavy enough to be stable without being inconvenient. I use it alongside a Space Mouse and an Intuos tablet for graphics work, and it's a great addition for anyone who loves trackballs.

After accidentally spilling water on my previous trackball mouse and rendering it unusable, I found this one as a replacement. Before purchasing, I was impressed by a video review highlighting its wrist-friendly design. This mouse contours better to my wrist and hand compared to my old one. It's perfect for someone with small hands like mine. I highly recommend this mouse to anyone with Carpal Tunnel Syndrome or similar hand issues.

Having used trackballs for years, this one is by far the best I've ever purchased. I've already ordered two more. Its operation is diamond smooth and flawless, making it the best trackball I've ever used.

Having a large collection of trackballs, I used to switch them out frequently due to declining comfort. However, this trackball has changed that. It doesn't try to reinvent the wheel with inferior designs; instead, it's a direct copy of the classic Microsoft Trackball Explorer, which is arguably the most comfortable design ever made. I don't see myself using any other trackball design. Despite its price, this trackball exceeds expectations in quality, especially the scroll wheel, which is often a weak point in similarly priced devices. It doesn't feel flimsy or noisy. In terms of quality and price, this is the best option available.

I find this mouse extremely comfortable to use, especially because I prefer using my fingers to move the track ball.

The ProtoArc Trackball has pleasantly surprised me with its smooth, refined, attractive, and comfortable design. I particularly like the bright orange scroll wheel and the RGB lighting, and the switches feel high-quality. However, the placement of the connection selection switch and the illumination switch could be more convenient if they were on top instead of underneath the device. Adding padding to the palm rest would also be a nice improvement. Overall, it's a very good trackball and is priced reasonably.

The mouse operates smoothly and maintains a strong connection, even though the receiver is placed under the table. It's a bit slow, requiring an increase in cursor speed, but that's a minor issue. It's quite large, making it perfect for slightly larger to large hands.

The mouse meets all my expectations. The price to performance ratio is satisfactory.

I've been searching for years for a trackball mouse that could replace my old Microsoft trackball mouse, and this one finally does the job.
