Is anyone having issues with the buttons breaking in Razer mice? I have a Diamondback, and the left mouse button broke - a piece of plastic under the button has broken and it pops up. Happened after about a year of use I then bought a Lancehead and in 2 weeks, the left mouse button has a crack across it - about 3/4 inch from the front of the button. Took it back to the store and brought another Lancehead home. That one lasted on week before the button cracked in the same place. Yeah, I may click hard, but never had a problem with any cheap mouse that came with a computer (Dell, Compaq etc) - I have several 10-15 year old mice that still work. The Razer mice may be pretty, but they are not rugged. Is Razer designing mice for pre-pubescent girls?
