Query: I would not buy this model again

I think the treadmill is very compact and motor is quiet however after only 5 hours of operation if that, the computer went out. I had not used this treadmill in six months so my warranty was out. Customer service is nice but now they want extra $100.00 for computer after only 5 hours of use.I suggest really testing this out before your warranty goes out.
