Bought to give for Christmas, I assembled the elliptical. First I wanted to check if all the parts were present, no surprises there, then I rode. Difficulty for the assembly of the fixing mechanism on the left pedal. It took me some time to realize that the thread was left (while all the threads are right on this), then no problem, but a pity that this is not specified in the leaflet. Otherwise, the device looks okay. I note 4 stars because it has not been used outside of a test that I conducted and which seemed to me conclusive.
