I have a Logitech G15, the old ones from like, 2 years ago (greatest keyboard in history) I feared it's breaking the whole time, so, I bought 4 more the next day. I still haven't had to replace it. Yet, on my new computer that I needed for music, I bought another G15 to test out the new ones, I've had to send it back in to logitech 3 times within the last 2 months. In which case, it's a total P.O.S
