I use an MX and I have arthritis. It’s one of the few mice I can use for a long time without my hands hurting.

Also play borderlands, get weapon that shoots as fast as you can pull the trigger, set fire to scroll wheel and blast your way through hordes of enemies with free scroll lol.

I have one and I like it Not super competitive when it comes to shooters or anything like that, but everytime I do play a shooter I have no problem with it

I have an MX Vertical and like it pretty well, but the only other vertical mouse I tried was some knock-off from Amazon that died after a couple years.

MX user here, imo the MX is to bulk for constant FPS. Feels like your throwing a rock around. I preferred the size and weight of the amazon cheapy especially considering how much the MX cost. It’s a nice mouse just not a great gaming mouse for long sessions again just my opinion
