We bought this treadmill a year ago and my husband and I use it when the weather outside is bad. It does not get used all the time, but my husband is an avid runner so when he runs it, he is on there for at least an hour at a fast pace. It starts beeping for no apparent reason after he has been on it for a while. All in all, we are very pleased with it! It is very sturdy and was significantly less expensive than the other machines of this quality.
