The belt becomes off center and needs to be adjusted after every use, and sometimes mid use. It seems like it’s going to slide into the side and will make a noise if not adjusted, and once adjusted back to the center it doesn’t take long for it to slide again. I understand you get what you pay for, but this seems like a pretty standard expectation in a treadmill, not something fancy.Aside from that it is great. It’s very small and is able to fit under my bed when folded. It is narrow but that’s never been a problem for me, I have accidentally stepped off only once or twice after many uses. The power is great. I would have no complaints if it weren’t for the slipping belt.The assembly took 60 seconds I used it right away and it works like a charm can’t believe how good it is especially for this pricePerfect for smaller spaces. It folds up very small/narrow. Works well. It is pretty small, both short and narrow, which is what I wanted, but for someone looking for a larger/full size treadmill, this isn’t for you. I’m on it almost daily (gotta get in those 10k steps). It’s perfect for what I wanted. Great compact treadmill for walking (I’ve jogged a few times and it’s fine for that too, but probably not for running). Excellent value for the cost.This treadmill is good for walking and the price is good for what you get. The belt/treadmill surface is very narrow though. For an average size adult the belt width barely covers a normal walking stride- I have actually fallen off a few times when not totally focused on walking perfectly straight forward.Screw knob to hold rail up does not fit more than 1/4th( if that) the way in.(see picture) Also I would like to have it corrected without sending treadmill back. The belt often needs to be adjusted to be centered. It is quiet when running and a good size for smaller area. Haven't noticed a lot of shock absorption. Would be better if programs had a better description other than dots graphed. Power appears to be as advertised. I bought two year Sporting Goods protection Plan and have received nothing. You ALWAYS have to adjust the belt after every use to center.I am so happy with this purchase it is easy to use and to store even in a small apt the seller is wonderful too when we received the treadmill one of the knobs was broken as the plastic was smashed and the seller responded right away and was willing to ensure we were happy with the product they are replacing the knob and even,offered to send a replacement treadmill so we wouldn't have to wait but the treadmill works great purchase and a really good price tooThe most important function I was looking for when I was browsing for treadmills was the incline. This treadmill barely has that. I was skeptical about this function even from watching the video included on the product page, but I figured perhaps the video didn’t do this treadmill any justice. The instructions weren’t that great either. Knobs should be labeled. Will be returning. Very disappointed with this purchase!I used this treadmill for a few days. It's very convenient to use the monitor to put your mobile phone or iPad. The most important thing to me is the thickness after folding is less than 30 cm. I can put it under my bed so my baby can't touch it. Also, it doesn’t make too much noises and I can use it when my baby is sleeping. I really like it and highly recommend this treadmill.
