Wish I had read this before I bought it... I use the treadmill mainly in the winter for running. I'm not that fast, nor that big but I am now having the motor replaced for the third time. The motor has a lifetime warranty but that doesn't cover the labor. Major bummer!
Check and compare Treadmills here before you buy any.
Check my pricing, ongoing promotions, manufacturer, mark and model, etc then make a decision.
