Hey everyone, these are just my first impressions of the EM11 Pro but i intend to make a full review as well as a few articles on my substack for this mouse and the ergo design in general. Thanks to ProtoArc for sending me a unit when i told them i was designing my own mouse and having such great communication. One of the best brands I've encountered regarding PR for sure.

First thing that hits once you hold it in hand is the build quality. Like, damn. Logitech can go suck their thumb in a corner somewhere, ProtoArc knows how to make their stuff. The travel of the clicks, the play of the buttons, the tension of the wheel, the coating of the mouse, the weight distribution. All genuinely first class. After experiencing it, only a single mouse felt satisfactory to use and it was the M3K, which is very far from the rest of the market. 

Once in use though, I have some issues with the very design of the mouse. I've been a long time MX3 user, and the resting angle of the wrist being closer to a traditional mouse makes it very intuitive to use. On the EM11 Pro though, your wrist is turned to a much more significant degree, meaning your fingers don't rest on the clicks. You have to use tension to maintain them on the mouse, else gravity does its thing and your fingers just drop off. Same goes for the thumb side, the side buttons serve as a ledge but you can't fully rest your fingers on the mouse itself. 

For occasional mouse users that do use the keyboard for most of their work, I can see it being a non issue, but for anything remotely varied in the computer environment it becomes very unpleasant to use. 

It's not a matter of the force required to operate the mouse, but the constant tension you induce and the pain that comes from repeatedly maintaining it over the workday. 

In my articles over on substack I want to go way more into the design choices, comparisons with my mouse project, etc but I run after time at the moment. If you want to follow along you can come over at https://tekneperipherals.substack.com/ and have a good time. 

Thanks for reading, you're more than welcome to ask for anything i didnt cover !
