The max speed is fine. The CPI is more like 500 not 450. The Kingsis lens (or possibly the non infrared LED) increases LOD on red cloth mouse pads, whereas the standard lens on a DeathAdder reduces LOD on red.
The mouse isn't what people want it to be. So for those who would have bought an AM if it wasn't so thin are going to be disappointed. Which is not something surprising. The front is something like 60mm and the rear is like 64mm.
The problem with the mice, the AM and the modified AM (FK), is that it is 58mm at the narrowest. The FK is smaller than the AM! Although only by a millimeter in length and rear width -- with exception to height. It does have nice touches to the design but it isn't the AM people want.
Would I get it over the AM if I didn't have one? Probably, because of the stress relief.
What I like is: the grooves to the finger area, the mouse wheel groove, stress relief, the angle to the bottom edges, the top shell piece for the buttons and the side area in the front.
If I could get one that is like 131mm long. 41mm tall, 61-62mm front, 60mm middle and 64mm rear. Also to remove a lot of the bottom material like the EC to stop the mouse from bottoming out when used on a not so level pad (debris). Oh yeah -- and a standard lens.Edited by popups - 1/24/13 at 1:17am
