This machine has so many uses I wasnt sure what to expect. When I started I cranked the heat and light settings way up and spent and average of 40 minutes a day for 10 days and lost (no lie) 20 pounds. I dont know how, ok I sweated alot, turning every 5-7 minutes. It felt like I had done a work out every time is was done, and as an added bonus my neck and back pain had went away. A work out and pain therapy who could ask for more. After awhile my time spot was needed so I stopped going but the weight stayed off for a good 8 months and the pain for about the same amount time as well. Awesome!!! I recommend the the Photon Genius to everyone.
