We've had an EXP3000 for almost 5 years and I think it's possessed because it simply stops on it's own. It will work fine for about 5 min. and then simply stops. I would NOT recommend this product to anyone. Five years sounds like a long time to have a treadmill but it's only primarily been used for walking and for a cumulative 3 out of the 5 years, it's been collecting dust since it's only used sporadically.
