I just ordered this, there is also a video with the guy running on a treadmill and using it. I will try it both with my myvu, and might try to test with someone else's treadmill. - David Lynch

i own it now, i havent used it much yet bcuz my right had carpal tuel has ot healed, im glad i have it, ad will test it later, but its not for someone with carpal tunnel issues though, but the scroll ball is nice - David Lynch

I highly recommend this device for any extreme computer user, who would like to learn to control their computer while stretching a bit, or standing up, but not having a standup desk, if for no other reason, to see continued improvements to this already decent product. - David Lynch
