Summary: Haven't used it as much as I had hoped. someone else s review said it was quiet. The vibration is loader than I had anticipated. I wanted to use it while watching my soaps on TV but not quiet enough.
Summary: Having not exercised for years due to spinal disintegration, osteoarthritis, lack of bone density, disc bulge, etc. etc. I needed something very gentle that I would USE. I find this easy, that I WANT to use it & feel so much better when I step off I just want to get back on. If it works in space for NASA I hope it works for me.
Pros: Convenient, Do Not Have To Leave Home, Easy to use, Love The Feeling After
