Proform 990 CSE Elliptical Review
TREADMILL DOCTOR NOTE :
The Proform 990 CSE is the best value of Proform's rear drive ellipticals.
The power ramp on the 990 CSE is a nice touch and has been fairly reliable in practice. The biggest problem these machines have is glitches in the iFit software and bearings failing in the main flywheel if they are installed improperly at the factory. You will also need to apply loctite to the shoulder bolts where total body arms attach to the machine to prevent the bolts from backing out and making the arms loose.
