Great product and awesome value! The unit delivers everything advertised and the results are amazing after use in just day one! Family member was having knee issues and pain in both feet. After 20 minutes of use the pain levels were dramatically reduced and walking appeared to be much improved. I personally used it for one of the programs and was amazed by the results after just one session! I could feel better tone in my calves and thighs without the normal gym workout routine. This product rocks! I highly recommend this unit for elderly and sedentary lifestyles. It is easy on the body and delivers amazing results. BONUS...it fits very comfortably under my desk as well! If you have feet, ankle, calve or knee problems, this product may improve your lifestyle starting day one!
