BurnOutPC.com has just posted their review on some XTracPads Accessories
The goodies XTracPads send me were really effective in making my mousing experience a lot better. The MouseGrips are something that I use daily on my MX510, and I won't take them off ! Their great. Looking at the MouseDotz, it's just a matter of preference, their pre-cut and fairly thin so they should stay on your mouse for a long while, but teflon tape works just as good and comes with any mouse pad you buy, also with a XTracPads. The Instaglide does make your mouse glide better, but it also requires constant swiping of the bottom every few days so I wouldn't really want to do that. But yeah it works. Overall three nice products, I was most impressed by the MouseGrips.XTracPads Accessories Review
