saxophonethoughts on mm710?
It's quite nice in how lightweight it is and I liked the smaller shape of it with the hump towards the back.
The problem with it though is quality control, the first one I ordered and the replacement both had coil whine which isn't a huge problem unless you don't have you headphones on then it's kinda annoying. The first one I got also, unless it was just pure chance since I did change multiple things at the same time, caused my computer to hard-lock and needed me to shutdown the whole thing. I sent that one back as well as changed other things so I have no clue if that is what caused it. If you buy through amazon though they are good enough with returns/replacements that I got my replacement before needing to send the first one back. Also apparently the mm711 improved the QC but it is a little bit heavier from the added RGB.
In the end as long as you are fine with possible return process as well as the possible coil whine, then it's a great mouse if you like the shape and size.
