Bests & Worsts Reviews from Amazon

The mouse itself is excellent. I don't like having to install special software, but I can even deal with that. But seriously, why do I have to create a user account with Razer just to use my mouse? It's ridiculous. If I had known this beforehand I would never have bought this mouse. Edit: Also, after a bit of use, I find myself accidentally hitting the DPI adjustment buttons more than is acceptable. They're right behind the scroll wheel, and very easy to push with the base of your middle finger when scrolling upward or just resting your hand on the mouse. Unexpectedly shifting DPI mid-movement will really throw you off.
