Are there side by side pictures of the Mamba and any of the Logitech mice around, or maybe of it side by side with the DeathAdder? I found plenty of G5/Deathadder pics, so I have an idea on the size difference there, but can't find diddly about the Mamba.
My google-fu is failing me.
I can go grab my mx revolution and get a shot next to my mamba if you want.
