Finally got my Mamba...
It's already a week but have only used it for few days...
From my point of view (comparing to Copperhead)
-love the size of the mouse, suits my hand nicely..
-Wireless Rocks!
-Love the design of the mouse and the docking station is freaking awesome
-Very smooth and Fast(5600Dpi

)
-Nice Packaging
-rubber grip at the sides
-pulsing lights from the dock
Things i didn't like
-No pulsing Razer logo on the mouse(i know this would make the battery die faster but no pulsing logo!)
-It'll go to sleep by itself which i don't mind but it's a bit too fast..
-It gets dusty at the bottom quite fast compare to my copperhead
-mousefeet quite thin and no extras from Razer
-Wish the dock was a bit bigger
Overall quite a good mouse but still pricey
It's just like DA but with wireless...

EDIT: Everdying, please update my razer list.. thanks
mind to swipe ur mouse on exactmat a few time on fps games (by lifting ur mouse up from the surface) . . and see if ur mamba's sensor stop responding a while? I got 3 mambas and all like this . . haha . . but anyway with a 5600dpi mouse . . guess we dun have to swipe our mouse . . juz curious to know . . cheers =)
