Ok, i have a wireless microsoft optical mouse special edition and it worked good the first 6 monts. But after that, it began to lag like crazy and sometimes stop working. I switched the batteries many times so that isnt the reason. Ok, so i need a new mouse. I play far cry [multiplqayer] and Condition Zero mult. Is the logitech mx500 mouse good for gaming? And does it stay good after 1 year of usage? Thanks a lot.
