For a mouse that costs $80, this was a disappointment. I love the design, and ergonomically speaking it's a great device. But the switches wore out after 1 year, which is unusual.. I've had many dozens of mice, all lasted for years before showing similar problems. And when I attempted to RMA it per their warranty, the service has been terrible and slow. I really wanted to like this mouse, and for the very brief time that it worked, it was great. But I won't trust Roccat's brand again.
