Excellent product, big downside: premature wear
I gave this mouse to my husband two years ago, and so far it's suited him perfectly, especially as it's very difficult to find mice with more than 12 buttons. Unfortunately, the scroll-click function started to malfunction very badly (it only works about once in twenty times), making it almost impossible to use in games. I'd bought this mouse to replace my previous model (a Naga Trinity) which had a right-click problem. It seems that Razer has a problem with premature wear and tear on the buttons, which is also reflected in other reviews. But it's not so bad that it happens every time just after the warranty has expired? it's probably down to bad luck, but it's a real shame considering the quality of the product and its price.
