I used a fatal1ty mouse for a long time about three years it still works great, but I recently upgraded to a RAT7 it doesn't seem quite as smooth as my old fatal1ty mouse but it's fully adjustable DPI up to 6400 DPI and the size and shape of the mouse is adjustable also which made it nice I could adjust it to fit my hand and another thing I like about it is it came with 45oz of weights, I like a heavy mouse... Just to give my input
