Quote from MaanManIt has lasted my two months of extreme abusive use with out any hitches, until the mouse wheel started squeaking a few days ago.
Wtf are you doing to your mice?! I've got the full fat sensei, and the mouse wheel started to squeak a bit as well, it's since worn down a bit and is absolutely fine. I've had my sensei now since... 2012! Wow, longer than I realised.
Quote from BeckCan't say I've ever had a problem with a Razer mouse. Had like 5 of them now and they've all lasted me years.
Facebook might not be the best place to reach them? Twitter or email might be better? I'm sure they'd want to sort you out.
Razer have notoriously bad customer service. Great products while they work, but I know plenty of people who look to avoid them entirely on the off chance something does go wrong.
