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.

Very impressive, very smooth. Excellent quality for the price point. Highly recommend

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.

A great product with good battery life. Reacts well to touch and is comfortable to use.

Best trackball mouse on Amazon.I have tried various other brands: Elecom, Perixx, Logitech. This Mouse is superior in terms of ergonomics, affordability and compatibility.As an improvement, I would like to see a more premium version:1) With better switches, the mouse buttons don't seem like they'll last - but I could be wrong.2) A wired option.Overall very impressed by this ProtoArc mouse. Definitely recommended.

I love this mouse! It has helped a lot with neck n shoulder pain. And paired with a smaller keyboard I can keep the best posture. Buttons are easy to click, rollerball takes a little getting used to but after a while you don’t even think about it. Changing the sensitivity is quick n easy with the little orange button n useful when using software for design or animation.

Easy to setup and comfortable to use. It is a downgrade from the Logitec MX trackball that this was replacing. The mouse movement isn't as smooth regardless of what DPI you select, the trackball isn't as smooth for moving with your thumb. But my biggest issue with this device, is that it connects to three devices. If you are buying this, it is probably the feature you want the most. So why is the change device button underneath the device! You physically have to pick it up, which isn't easy due to the ergonomics of the device and press a tiny button each time you want to switch. The Logitech had a easy to reach button next to the scroll wheel.

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.
