This is a great value for the money with one very important caveat. The frame and treadmill is very small. In its price class, it is actually a larger one than most. But for a full size man or teen, the belt area is very narrow and is short. With the manual incline adjustment flat, or level, the belt area lifts you up so that the grab rails are below your hands. That being said, it works well. It is a very simple design and doesn't do much but the motor is strong and the running isn't too noisy when it is going faster. It goes together well without much effort. All in all, in the sub $400 price range for home treadmills, it is a leader in that segment. But, if you are a larger person, or have larger people in your family, I highly recommend spending more money to get a larger device.
