Good to hear. This mouse seems to track better at 400/800 than my other mice, at least on my surface. I may test it on my Hayate later on. The more I use this, I think if you can used to the shape, the construction and performance is really nice. Hopefully it gets more exposure as I think it's a good alternative to the G400/DA with good quality hardware.
Maybe someone with more knowledge can pop up an official review thread ala the Zowie AM, DA:BE, and others?
