Pros: Feels good. Very solid feel and weight. Moves nicely. Very configurable especially with 3rd mouse button.

Cons: Was faulty at first. Took 2 of them before the problem was figured out. Initially if I set the software to remember macros on the mouse's on board memory the mouse would jump to random locations on the screen. I had to switch the software to remember macros on my PC instead. Initially this was very frustrating and angered me. Now that it is fixed I love it.

Overall Review: Replaced my Naga with this. Happy with it so far. My Naga mouse stopped clicking a month after owning it then died completely 6 months later. This mouse feels much sturdier.
