I bought this about a month ago and I LOVE it. I try to use it as often as I can, this is great because it's Summer and WAY too hot to go out and walk.
I just purchased this for myself to use with my arms and I love it! Yes it does move on tables without a surface to catch on to but that can be fixed. Totally worth the price!
My bought this for me 2 years ago. I put It on the table to use it with my arms since I'm in a wheelchair and it's hard to find exercise to keep my hard rate upand it moves.
I bought this stationary bike for my boss who had knee surgery. She was sitting too long at work and her knee would swell. Now she exercises her knees while working and it is helping her heal faster. She is very thankful for it.
I bought this a few months ago, and it is fine for arm exercise. However, the key won't tighten enough for giving good resistance, and the pedalling is too easy for me. I had not expected that from the description.
