My trusty diamondback is 4.5 years and still working well, just that it's a bit worn now, clicks sometimes need to be harder but that''s only recently. I have since decommission it in favour of my new Roccat Kone [+], awesome mouse, but still misses the familiarity of the Diamondback. Every mouse maker has complain from consumers, and I believe after searching online just confuses you even more. Just get a mouse in which the design is to your liking, and if possible, feels comfortable in your hands, like trying out your friends new mouse will help you to decide.
