Top critical review
Not great. Not even good. There are way better brands out there.

This mouse made me go back to using Apple's Magic Mouse, which is saying a lot because the Magic Mouse is the reason I switched to a vertical mouse in the first place.
Positives first (there aren't many)... This mouse is okay ergonomically, and eased my wrist pain (in conjunction with a cushioned wrist support). In every other way I would not recommend it.
Now the negatives: First, and the most serious complaint I have, is that it sometimes prevents my computer from booting up (I use Mac, and I have all the up to date drivers installed). At first I thought my iMac was broken - the loading screen lit up but then the boot-up process stalled out. Then I noticed the green Evoluent logo (which lights up green) flashing. Unplugging the mouse then allows the computer to boot up as normal. This happens sporadically, with no real rhyme or reason to it.
The second complaint I have is that the materials used for the buttons seem to attract all manner of grime. I'm a clean person, and wash my hands pretty regularly, but somehow grime seems to build up on this mouse. I think it's in part due to the 'sweatiness' of the shiny plastic, which is really unpleasant to the touch. I have the least sweaty hands, too... they're usually cold, and I definitely don't have clammy hands! Maybe it's build up from hand cream? Either way, I found myself having to clean (and being a clean freak, disinfect) all the time, and I haven't had this issue with any other mouse in my life.
It gets more than just a single star only because the ergonomics are... meh. It's okay. It doesn't outright hurt my wrist like normal mouses (mice?) do. I've since bought a different brand that looks more like a shark fin, and it's WAY more comfortable to hold, and doesn't have the issues I encountered with the Evoluent, and it was less expensive.
