    I generally do not write reviews but this treadmill/walking pad is perfect for what I needed. Its a perfect size for our small house gym. I opened the box with my son and all it needed was a few screws and very easy to manage. I have used it a few times already and it has Bluetooth if you want to watch or listen to something on your phone. The only negative thing for me is that its missing a cup holder. The area I thought was a cup holder is angled so you cant put an opened cup there, just a closed water bottle and the place you would put your phone is blocking the screen to control your speed etc, otherwise well worth the money.

    I received this about a week ago and I am finding it to be loud and the belt appears to be slipping to the right. I see other customers have complained of this in their reviews as well,. i’m disappointed as this is my second serenelife treadmill. The first one I had worked very well, but I gave it to a friend as I wanted to get a newer one. Needless to say I’m a little disappointed that this is so loud and I should’ve kept the old one. I will probably be returning this and looking for a different treadmill to buy.

    I purchased this treadmill a little over a year ago and overall I will say that I am glad with my purchase. That being said, I do believe this is suited for certain situations so it may or may not be good for you. I bought this because I wanted something to use at my place while I played video games since I would instead just be sitting around for hours. But I live on the 3rd floor of an apartment complex in a one bedroom, ~750 sqft unit, thus I also needed a treadmill that would be quiet/not produce a lot of vibrations and small for space saving and when storing. Since I game while using it, I am not going very fast on this, I have worked my way up to roughly 3.5 miles/hour while still being able to play my games well (ie. FPS and still hit headshots, etc.), although more on the speed below. Therefore, for my specific needs, I think this treadmill has been perfect. Using this, plus eating better, I've lost roughly 20lbs (BMI 27.7 > 24.5) and feel great. Assembly was not too difficult, I'm by no means an expert at building things (although I was the one to help my dad with assembling things growing up), but it took roughly 30 mins to have everything up and running. I don't think you need to pay for expert installation unless you have never assembled anything in your life. Once built, I added lube to the belt and was off and running! (well fast walking). I did purchase a rubber mat to place underneath to protect my floor and reduce vibrations for my neighbors below me (I have asked them multiple times if it bothers them and they haven't even noticed I'm on; please ask your neighbors if you decide on purchasing one for an apartment/shared living complex, it's the nice and right thing to do) and you can check out my review on the mat as well if you'd like. The treadmill itself is smaller and slimmer than the normal ones you see in gyms so if you're very tall or heavy, this may not work for you (I'm 5'8, 160lbs; was 182lbs and it works for me, but I think if I was closer to 6'0, the small size might become an issue in terms of comfortable stride length). The biggest "issue" for me is the narrow width of the belt, I did have to get used to it, but I think this would be an even greater issue if I tried to run on this treadmill since when you run, your strides are less compact and you could step outside the belt by accident. Now in terms of speed, the treadmill is adjustable from 0.1miles/hr until 6.0 miles/hr, but I'm honestly not sure how accurate those speeds are anymore after 1 year of use. When I first bought it, the speeds seemed accurate, but over the last 2-3mo, I need to turn it to 2 miles/hr before it even moves much with my weight on it (moves well at any speed without me on it, but now if I'm at 0.5 miles/hr for example with my weight, it won't move at all), so I think this is a motor problem and I'm def worried if it will die out on me in the future. Therefore, now I go up to "4.0 miles/hr" and I'm not sure if I've just gotten used to it and am in better shape with better stamina, or if it's actually 3-3.5 miles/hr with my weight on it. It wasn't doing this when I first got it, at which time I was heavier, so I believe it's the motor. I have been periodically re-lubing it, and I found a good lube for it, you can check my review on that as well! The treadmill will automatically stop at 60 mins (1 hour) but you can restart it right away. There's an Android/iOS app that works with the treadmill to complete running programs but I don't use it at all. All in all, this treadmill has given me exactly what I was looking for, and at a price I think is well worth it (was ~$250 when I got it, so it's running at ~$19/month at the moment since I've been using it for 13 months thus far, which I think is great value, and obv will continue to get cheaper as the months go by). If you are someone with similar needs from a treadmill, I would highly recommend and I would buy again if needed!
