This particular product in question, the Air Climber, was purchased less than a year ago and broke almost breaking my right foot. The cheap plastic is a waste of money and it only carries a sixty day warranty. When you call their customer service it's labored out to people from India and I truly don't think you are actually calling the U.S. So read the actual reviews before your out one hundred or so dollars. This product seriously needs to be taken off the market so people don't spend their money and time. Take a tour on it at your local sporting goods store before you even think about purchasing........
