I have had a home unit since January 2006. I used it every day for the first 3 months and then 3-4 times a week thereafter for about 6 months. I am pre-diabetic and I also swear by it. It is not cheap to buy, but my insurance company picked up two-thirds. When I am on my feet alot, the bottoms hurt. At night, I will then use the unit. It helps blood flow better.
