Before I bought this I read reviews that were somewhat mixed, but given the moderate price, I decided to go for it, and I'm glad I did. It might not suit someone who is athletic and in great shape, but for someone like me, out-of-shape and partially handicapped, it's ideal. I don't have to worry about getting to a rehab facility or falling, yet I can get a good cardio workout and move my arms and legs. The timer set up is confusing and not explained in the directions, and it seems to be broken after only a week, but I would still recommend this machine. I just use a clock. I believe this would be a huge benefit for the millions of out of shape people who are intimidated by more sophisticated workout machines and fancy gyms. I think it will be a real Godsend for my health. The tension can also be increased to make it more difficult as I progress. For the relatively low price, I heartily recommend it.
