Proform Trailrunner 4.0 Treadmill Review - $1,999.00

The most expensive and the best Proform ever made. Proform has promised that "this time" their service is going to be better. We hope that's true.

The warranty on the Proform Trailrunner 4.0 is very nice. Labor is covered for 2 years, parts are covered for 5 years, and the motor and frame are covered for life. This is the kind of coverage you see when a manufacturer has faith in the product they produced.
