Proform Performance 400 Treadmill Review
TREADMILL DOCTOR NOTE :
For someone who is going to simply walk'and do not do too much of that or you will need the Treadmill Doctor.
The warranty on the Proform Performance 400 is pretty bad. Parts and labor are covered for 1 year, the motor is covered for 25 years, and the frame is covered for life. This kind of coverage shouldn't inspire any confidence in this treadmill.
