works as promised
I just got the unit and shoes today. Mine work fine, sitting at a desk. (some had complained that you have to be standing). They work better if you can press your knees under the desk.  You do need some weight on the feet, so if laying down, you'll have to have something against your feet. Not sure why the 'pads' aren't higher, or why the shoes have the nubs. Or if they really get in the way. I don't think I'll be walking around in these, tho you could. But as stated, they are working fine. I have the machine about half way up. I started to feel it at 25%. At 50, I feel a noticeable tingle.<br />I hope to report back on how effective they are. My 4 stars are only saying that it works as promised.
