ProtoArc Vertical Wireless Trackball Mouse, EM05 Bluetooth Ergonomic Rollerball Mouse Rechargeable Computer Laptop Thumb Mouses, 3 Device Connection, Compatible with iPad, Mac, Windows PC

From the moment I opened the box, it was clear that this trackball is a premium product. The packaging was well-designed and robust, setting the tone for the quality experience that followed. The device itself feels solid and well-constructed, with even the smallest details reflecting its superior craftsmanship. The trackball is exceptionally smooth under the thumb, gliding effortlessly with minimal resistance. The buttons are precise, offering just the right amount of feedback, making every click feel deliberate and controlled. Ergonomically, this device is a game-changer. After decades of using a traditional mouse, switching to a trackball was a significant adjustment, but the comfort and reduction in strain have been well worth it. I can already feel the difference in my hand and wrist, which makes the learning curve a small price to pay. While it may take some time to retrain years of muscle memory, I am confident that this transition will lead to long-term benefits. I highly recommend this trackball to anyone looking for a high-quality, ergonomic alternative to the traditional mouse. It’s an investment in comfort and efficiency that I believe will pay off in the long run.

Works great. Allows for multiple angles of the arm. Can connect to multiple devices. Great product.

Nice shape more upright than previous trackball mice I have owned. Seems a more natural hand position. No hand, wrist or arm aches to report. Linked with computer well and no issues. Good mouse

It is a great product! Very comfortable to use and has a great construction quality. The only flaw I see in its design is that it's somewhat bulky. I'm a digital nomad, and portability is a key factor for me; to be honest, this one is huge! Not portable at all. Other than the size, it's a great gadget, seriously! I will keep it only because it's extremely comfy and satisfying to use.

Excellent Quality product, lovely solid feel to it and so comfortable to use. I was getting "Mouse Shoulder" at a PC all day, but not having to move my arm, relieves the pain. The button controls are also brilliant, with an extra forward and back button for web navigation on top of the usual zoom and L/R buttons.

My Logitech MX Ergo left click finally gave up and they one thing that I would have changed with that mouse was to increase the angle/tilt. So I decided to go vertical with the ProtoArc EM05, I can confirm that the newer NL version is shipped despite no mention of it on the page. The mouse isn't completely vertical, your hand ends up resting very comfortably and naturally at a nice angle. For me the angle feels nicer than the Logi MX Ergo and M575 that I have owned. While the mouse isn't heavy the wide base and grippy feet means that it doesn't move around in use. Easy to access and pop-out ball which makes cleaning easy. The switches feel soft/mushy and are quiet, not a massive fan of how it feels but others may like it. Downsides, no software. You can't customise the extra mouse buttons or change the DPI that the orange middle button switches to. Un-accurate senor, while you won't notice it for the most part but if you need to click on something small or do anything that requires accuracy or small movement then it struggles. Overall not bad for the price.

Way better than a standard mouse. It only took a couple of days to adjust and is so much quicker and easier to use than a standard mouse.

Good: - Solid and well-made - Nice and chunky - Ergonomic shape Bad: - The track ball is really scratchy when rolled, meaning that it is inaccurate. The pre-selectable pointer speeds are either too fast or too slow, meaning that navigating anywhere is difficult. - The mouse is simply no good for large hands with long fingers. My fingers extend well beyond the mouse and track ball, making it uncomfortable to use. Overall, I think I'll be returning this for something better.
