Razer’s latest mouse appends some strategically-placed buttons for MOBA (or DotA) games that you will probably forget to use. I’m not sure if anyone was actually asking for this thing, I personally don’t think the Q,T,E and R keys are that far out of reach, nor the 1-6 keys for items. I could see myself assigning these buttons to items, but its probably likely that I would sooner forget I even had the buttons to begin with.
I currently own a Razer Mamba mouse, I made the switch after a 6 year streak with my previous Logitech MX518 and I haven’t looked back. So I can personally attest to the comfort this mouse brings. It looks almost exactly like the Mamba except with the protruding buttons on the side. I’m also not totally sold on the slimy-green look, but somebody out there may love it. You can pre-order the mouse now for $79.99 and it will be releasing later this month.
