i'm currently using a thermaltake level 10 esports mouse. it's okay, i can grip it pretty well. the software isn't the best (ugly and takes eternity to load) but does what it does. I was using a g700s prior, but that mouse really would make me want to toss it against the wall. software half the time would not detect my mouse so my preferences wouldn't load. i switched to onboard memory, but half the time it would loose all the profiles. battery did not last the supposed day or so. Maybe i just got a dud, who knows. however, it liked the grip and the layout of the buttons wasn't too bad. if it didn't have all those issues, i'd prob be still using it.
the rat mmo7 was okay, but for some odd reason it would kill my wrist.
the razer naga i got a long time ago was pretty nice. forgot why i put it on the shelf. might have been due to that shift to cloud based mouse software.
