I have this one now. Does anyone know if this is the NEW revised version with better DPI?

I just bought the mamba (don't worry I didn't pay $120 out of my pocket for that overpriced thing) with a $100 dell cert that I couldn't find anything to use it on due to it not being eligible for use with instant discounts etc. People say the ergonomics are very close to the deathadder, what are your thoughts on the comfort level?

My friend got the mamba but for the price not worth it. This one is just as comfortable. I am very happy so far with my Deathadder no complaints.

I hate rebates!
