short: nice but potentially razer + razer addons = fail

long: Seems nice but given the whining on the interwebz about razer's inability to patch/update their old products (apparently they'd rather sell you new ones) and WoW's constantly changing nature the razer addons could be more of a liability than anything.

If the mouse can be used as merely a button repeater (not sure if that's the correct term for binding ctrl, alt, del, tab, etc., to it) then it would possibly be much more useful. If not it's dead in the water I think.

Either way (compulsory razer addons or not) I'd hazard a guess that the build quality is better than the steelseries mouse criticised on this and other websites.

People far more intelligent than me will probably work out a way to get it and a logitech g13 to work together so you almost never need to move your hands (reaction time FTW).
