TR4000i Folding Treadmill
- Product Review (submitted on July 15, 2013):
Pros: Stable, gym-quality ride, very quiet, easy-to-use controls, programs
Cons: Workout log website needs work
Bottom Line Reviewers say every aspect of the LifeSpan TR4000i -- from its well-lit, easy-to-use controls to its smooth, efficient ride -- is well thought out. The only exception is its online workout log/USB thumb-drive interface, which could use a little more development.
