This Machine Is JUNK! And Nordic Track customer service rates the same. I bought this treadmill and it lasted about 6 months when it quit working. I called Nordic Track and they sent me a new control panel that I had to install myself. The thing worked fine again for awhile and now it quit working properly again. It acts as if the thing heats up during a 20 minute workout and quits until it cools down before you can get it to work again. Anyway, I called them again and they said it is out of warranty and it will cost me over $600 to repair this rarely used Peice of Garbage. And Nordic Track knows there are problems with there products but are doing nothing to make it right. They will never get my business again.
