Despite a slight squeaking sound that is heard from 200km, I am currently over 900 and no signs of fatigue especially manifested, finishing quality is not exceptional but it is d a good value in general prices. The different resistance levels allow adapting efforts during the exercise sessions. I mounted the front foot backwards but apparently it does not affect the stability, some small plastic pieces are broken inside the mechanism but they ended up going out and cycling operation has not been altered , it should not be significant, only fixing lugs in my opinion.
