Free- belt just went after a Sears man did my yearly maintenance by lubricating under the belt with a wand. They said not responsible! Motor works great. Non smoking home. Inclines, heart rate check, miles, calorie burn count, adjustable speeds and safety shut off when key is removed. Wheels for easy transport. If you're handy and can put a new belt on for under $100 you have a $700 treadmill for free. Downsizing and dont want to take it.
