## Description

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

Review: Great ergonomic mouse - Used Apple mouse and started having pain in hand so got this. Learning curve is not that steep and comfortable.
Review: Excellent purchase - Best mouse I've had so far, used to own a Logitech ergo m575 which was good for short bursts of usage but for longer workdays I felt pain in my palm and the joints of my fingers, did a bit of research and decided to try a mouse with a more neutral handshake position and it's the best decision I've ever made, pain is gone! Also high quality build, smooth scrolling, great feel, all around quality product

### ⭐⭐⭐⭐⭐ Review
*by R***K on 1 September 2025*

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.
