Had two of these in the span of two weeks. First one, on my third use of it, the Fifth overall between the two of us, the left elli[ptical started falling off. No big deal, tookit back, got the refund, ordered another one. New one arrived within two days. Today, was using it for the Third time, guess what, the left elliptical started falling off. Kind of sad, while they were working, we both loved it. The dog wasn't to fond of it, since he thought we should be walking, Not sure if I want to try anything else at ths time.
