We sometimes get criticism for being overly harsh with our examinations of product. In that light I decided to re-write this review. I do not like core drive ellipticals ... period. Quantum's, or anyone else's core drive. Take a chance if you like some of the features or if you think that it will lend itself well to medical applications. For my money I will stick with a front or rear drive elliptical design. Believe it or not, this was less harsh than the original.
