I had the naga lose middle click after only about 18 months so I went back to logitech (using their mmo mouse now). I'll also add that I'm not super brutal. I prefer logitech software. Razr seemed to think they should be my social media outlet and updated all the damn time to no visible.

If you are hard on stuff, maybe try corsair? My aluminum keyboard (the vengeance) is going strong after 4 or 5 years with no problems besides being kind of gross if you look closely at it.

I should probably clean my keyboard.
