I just lol'd irl, where are you getting your statistics from?
Logitech is by far older than Razer and all of their products, or nearly, are 100% stable.
Razer has tones of problems.
Lucky you if you haven't got any, but most people will end having one.
Could it be a sticky key on the keyboard or a driver/firmware going nuts because of an update, you'll get a problem in most cases.
I'm not saying they're not good, in fact I have a keyboard and a pair of headset, which I think are awesome, but I had so many problems that I wouldn't choose Razer anymore, unless there's some major changes happening in the company.
