I just recently got the Logitech MX revolution mouse, the thing works great, its the coolest thing ever. I just have to ask someone who has had it for a while....how durable it is? because the scroll thing when its loose seems like it will fall out any minute, and the right and left click just dont seem right, also it just probably feels weird because before this i had a $5 mouse from target for a couple of years also with the scroll wheel i tend to click it repetitively just for the hell of it, would that make it worse im just a bit concerned\paranoid. also is there anyway to make the serch button make new tabs in firefox? or is there a way to make it cycle through tabs in firefox?
