Review: Fantastic choice for ergonomic trackball; I bought one for office & home - Basic description: essentially the trackball equivalent of the "vertical mouse." What do I think about it: Excellent. Ergonomic design is fantastic for me. Helps my shoulder vs. other trackballs because the angle of the arm impacts which muscles in the shoulder get used. It's just a comfortable, natural angle that allows my arm to be more relaxed while having good control of the cursor. This is also a much better value than the extra ergonomic Logi[tech] equivalent, which is nearly 2x the cost as I type this. And by the way, you'd have to use the cushion thing the Logi unit comes with to achieve a similar angle. Maybe it's great/fine, but if you want the steeper angle then why have a 2-piece design? Other aspects: Buttons somehow feel crisp while also being quiet. Effort feels just right to me. Weighting of the ball feels just right and it moves very smoothly. Scroll wheel could feel a tad tighter for my liking but this is being very picky; it behaves as I expect/want. Subjectively, the ProtoArc feels higher quality than the Logi M575 I'm coming from. The M575 doesn't feel cheap to me, but this feels nicer/higher end. If you like switching between DPI levels on the fly, there's a button on the mouse for this. I don't use this but the button is not in the way. My only open questions about this unit is how the Li-ion battery and buttons will hold up. The Logi units use plain old AA batteries, which makes them a non-issue to replace (though less convenient than Li-ion in some ways). The buttons fail on Logi units faster than I think they should. Time will tell here but I'm hopeful given that ProtoArc put the time and effort into creating a very thoughtful product.
Review: Great Trackball at an amazing Prine - Price and use of this ProtoArc Vertical Wireless Trackball Mouse are amazing. Very comfortable to use during long hours. Works wonderfully on PC with a wireless fob and on iPad with Bluetooth. So easy to use that my wrist is at a more natural angle. I’ve been using trackballs for close to 20 years, with different brands and styles, and this one has topped them all with the angle, button placement, and thumb control!

## Features

- Ergonomic Design for Natural Grip: The vertical design of a 62 degree tilt and natural handshake can perfectly fit the palm of your hand, keeping your arms and wrists in a relaxed state, so that you won't feel tired after a day of work
- Bluetooth & 2.4G Wireless Connection：PLUG and PLAY. This trackball mouse has triple connection modes(2.4G+BT 5.1+BT 3.0). You can control three devices at the same time, switch freely between Android, tablet and Mac with just one button. Note: all the buttons are non-programmable and the backward forward buttons are not compatible with Mac OS system
- Thumb Trackball Mouse: Equipped with a smooth trackball, move your cursor with your thumb movement instead of moving your wrist and arm. It will effectively reduce fatigue and strain for your wrist and arm. Not only work on flat surfaces, but also on your leg, sofa and other surfaces as well, especially in a narrow space, such as the messy desktop
- Rechargeable & Quiet Clicking: The vertical trackball mouse equipped with a build-in rechargeable battery, could be recharged easily with the included USB-C cable. Please remember to turn it off if you do not use it for a long time. Smooth frosted surface and quiet clicks can bring a better user experience and free your worry about bothering others and keep you stay focused while working
- Wide Compatibility & Adjustable DPI: This vertical rollerball mouse is suitable for laptop/PC/notebook/tablet/Macbook/ipad/iPhone. It is compatible with Windows, Android, Mac OS etc. 5 DPI levels (200/400/800/1200/1600 DPI) allows you to change the cursor sensitivity easily for more precise tracking
- After using the trackball for a period of time, please clean the trackball and the three white rollers inside the hole to ensure that the trackball is always smooth. Note: When the computer is just started or a large application is running, it may also cause the trackball to not run smoothly
- Warm Tips: Since it takes a learning curve to get used to the control method when using our trackball mouse for the first time, it may cause inconvenience to your mouse grip, you can experiment with different hand positions to find what is most comfortable for you. We recommend that you take 1-2 weeks to get used to it, as many users find that it will help reduce the pressure and pain on your wrist caused by long-term use of the mouse and improve comfort
- Please note that this product is designed as a pure trackball mouse, which is fundamentally different in its interaction method from traditional optical mice. It cannot control the cursor by moving the device itself like a standard optical mouse. Please read carefully before placing your order.

### ⭐⭐⭐⭐ A Great Alternative to a Std Vertical Mouse, as well as to a Std Mouse & to a Std Trackball Mouse
*by L***J on December 10, 2024*

I just received this alternative to a Std Mouse, (to a Std Trackball Mouse, and to a Std Vertical Mouse), and I must say it is all it claims to be in terms of use and functionality. The buttons work very well in their designed locations and the trackball ensures I minimize my hand/arm movements. I am enjoying the user experience. I had long ago moved from using a Std Mouse to using the Trackball alternatives, (of which I highly recommend the Kensington, Nulea, & Logi-tech options if someone is not ready to move to a Vertical Mouse). So while my current favorite option for a Std Mouse is the Logitech Ergo Trackball Mouse, when it was recently liberated (ie lifted/stolen) from my temporary workstation location, I decided it was high time to try the Vertical options available. I looked and tried several Vertical Mouse options, and although fairly comfortable with a few, I missed the use and functionality of having a Trackball Mouse. So when I discovered that Kensington & Logi-tech and a few other brands had some Trackball Vertical Mouse options I was thrilled. After reviewing the, (limited), options available I ended up selecting the ProtoArc Vertical Wireless Trackball Mouse, EM05 NL Bluetooth Ergonomic Rollerball Mouse for the following reasons: 1> A "true" vertical mouse setup with a 62' Tilt 2> A rechargeable mouse. Charging via a Type C USB cable option, with an included charging cable. 3> A 2.4 Hz Dongle along with Blue-tooth wireless connectivity options 4> Compatible with both Apple / Mac, Windows, PC Android, (this means in a pinch my significant other can use it as well for her Mac). As noted above I just received this mouse and have been putting it through its paces and so far, I think it's excellent. However, I am giving it 4 of 5 Stars, (as the system is not allowing me to give a 4.5 out of 5), for the following reasons: A> The trackball could be a little bigger even though it is thumb-specific, I have found the tracking of the larger trackballs for finger control tends to be a little easier to use, and therefore I would like the thumb trackball to be a little larger for that control. B> The Dongle could be set up for easier visibility. I find that keeping the Top and connecting edge Black requires a bright lighted area to ensure it is connected correctly and smoothly. So a brightly colored top and a white, (or other bright color connecting edge to the USB portion), would allow for faster and easier connection setup. C> Non-Programmability of Buttons prevents customization D> Lack of covering for the charging port and Dongle insert areas would be a plus from my perspective With that said, besides what I noted above, I also have the following recommendation: E> The creation of a Travel Size version of this or other Vertical Mouse. (As noted above I was using the Logitech Ergo Trackball Mouse and although it's big, I had a case for it so it allowed me to take it for some limited travel, so having the option to purchase a case would be a very good option. However, when doing serious traveling I defaulted to using a "miniature version" of the Std Mouse as space becomes a major restriction. So even with the feedback given above, I do want to stress that overall I am very happy with this ProtoArc Vertical Wireless Trackball Mouse, EM05 NL Bluetooth Ergonomic Rollerball Mouse, and I would highly recommend it to anyone, especially to those interested in transitioning to a vertical mouse and to anyone who would also appreciate having access to trackball functionality as well.
