Bests & Worsts Reviews from Amazon

Had good reviews. Highly disappointed. Only weigh 190 and I can’t run on this thing. The entire belt portion basically skips a beat whenever I step on it or even try to run at any speed and I almost fall off. I’ve had multiple people try this of various weights and they experienced the same thing. You have to catch yourself from falling off. Can’t even run on a treadmill which is its only purpose. Not sure if this is just mine or if it the product in general. Will be returning. And yes I put it together properly
