One of the sorriest excuses for a treadmill. If you live to be disappointed, Proform has a treadmill for you. Unless you have the walking habits of a normal 80 year old, try another machine.
The reason we are able to do very well is because millions of cheap treadmills are sold every year worldwide. If they all were quality treadmills, you would only need to replace wear parts and we would ship far fewer parts every year.
