I'd say this is overall 3 1/2 stars but I'll say 3. It's easy to assemble and fold down however the base gets very hot after using and starts to make an awful squeaking noise approximately 8 minutes into my routine. It does tend to slide (even on carpet) so I have to put the edge against a heavy piece of furniture but overall, it does the job. Periodically I do have to adjust the tension because it seems to loosen up after a few minutes but it is fairly sturdy and the pedals move well.
