Proform Performance 400 C Treadmill Review
TREADMILL DOCTOR NOTE :
A horror story under the motor cover. A cheap alternative for a Proform but not a very good treadmill.
If you need a cheap unit at a bargain price, this one is it but only will last if you are a walker and baby it. Our pick would be the Proform Performance 500 S at Sam's Club. It has better parts (although we use that term better with great reservation), a more freshened design and a better chance of holding up under light use. If you just want a machine in your home to impress your visitors that you intend to work out one day, than I think this might be the model for you.
