I used logitech in past, wireless one then the rubbery stuff at the side started to come off and blabla.. now I'm using razer imperator and it's seriously amazing.. so light and precise, love it.
duno i just hate how when its running out it keeps failing, last wireless mouse i had it kept disconnecting even tho it had battery, so i got angry and threw it at the wall..
I use a very old Dexxa Optical mouse. It has 5/6 years now... I bought wireless mouse to laptop but I'm not happy with it. It its batteries very fast :/
