heh im using a Razer exactmat
its pretty neat actually...i thought the 2 different gaming surfaces would be a complete gimmick, but it does actually work. currently using a logitech G7 lazer mouse, and the feet on this thing literally glide over this mat!
realy impressed with this mouse by the way. the feet are made from PTFE and instead of 5 little feet, there are 3 big feet. it properly glides around this mat im using. what i find particularly good is that this mouse tracks just fine on the glass surface of my desk. my old MX510 just stopped, but this carries on unhindered.
its solidly built, has the right amount of buttons, theres ZERO lag, works perfect right out the box, and you can take it anwhere.....i took it to the CAD lab the other day. just take the mouse, and the USB dongle (USB charging/base station need'nt come with you, it has a usb port on it for the dongle, so u just need to take the dongle) plug it in a computer and away you go
you can also change the sensitivity on the fly, great for games, great for CAD, i found it really usefull dropping down to 400dpi to do some finer work with it.
only thing i will say is that the battery life is a little short.....good thing they supply you with 2 batterys!
(sorry about that.....had to get it out. im am truely impressed by this mouse)
