I bought this treadmill 4 years ago, and it just recently started giving me trouble. I tried to call customer service, but after being on hold for 10 minutes they hung up on me. Then I emailed, and it has been over a week and I have gotten no reply. I also called again and left a message this time, but no one has returned my call. Lesson learned: you get what you pay for, and this treadmill won't last. There is NO customer service either. Big mistake.
