This is our second device - same model - our 1st device was MUCH quieter, and the transition ftom L4 to L5 feels like a jump from L4 (way too easy), to the highest level almost impossible to pull. It sounds (to us) that a bearing is flailing around inside the motor. Customer Service was not much help. Their suggestion was to change rooms (silly because the device is in a gym exactly where the last device was). They did offer to extend the satisfaction period to 3 months but its unlikely anything is going to change. Is it possible we just got a lemon device? They should consider that (manual says it shouldn’t be noisy). We will likely return and re install our older, but same model. The only reason we replaced was because the cable/rope seems to have shrunk with age and gets tangled. 🤷
