Excellent choice for its price! It has a program from 1-12 where 12 is fast enough for light jogging! For a home treadmill, it's worth the money, of course, if it doesn't have any issues! It is also quite impressive in terms of its appearance! The only complaint is the app that cannot connect to anything; once you connect, it tells you that you need to log in via Facebook, and if you don't have it, you can't log in. It also says that you need to download another app which is in Chinese, so you can't make sense of it! Furthermore, the app is not available on the app store or the Google store, and you have to download the app in apk format via Google... now if someone has managed to log in, please send details!

Quite satisfied after a month of daily use by the whole family, walking and light running (7-11 km) and maximum user weight of 82 kg. It has a bit of noise but it's not too bothersome. Problem with the threading in the tightening of the arm (can be solved with the use of another screw or using an allen wrench). The importing company and its technician were helpful, with prompt response to the issue I mentioned. Frequent lubrication with silicone spray. Conclusion & personal opinion: A worthwhile purchase for users without particularly high demands. Time will tell.

It is excellent for its price, I don't understand why there are some negative comments. With that amount of money, you can't get a good treadmill and yet, well done..!!

Update 1 year later
Nothing has happened to it, it is just like when I bought it, and I use it daily.

As a treadmill, it is very nice. What bothers me is that after a week of use, the plastic between the belt started squeaking when I step on it... Another thing is that the screws holding the two arms with the frame were not easy to screw in... I had to use a power drill to screw them in...

Well, I'll be brief, the treadmill is worth its money. The only issue I noticed is that if you weigh 90kg and above (I started at 93 and reached 85, along with *diet*), many times the belt momentarily slows down (speeds of 10 and above). I believe that up to 85kg it's fine, otherwise you should go for something more powerful.

It is exactly the same as the Upower Marathon 21. Chinese style, something that is evident from its construction quality. Not particularly sturdy although heavy. Cheap plastic of toy quality. Thin and relatively hard carpet. The legs are of very poor quality, almost nonexistent. Overall, it is a mediocre treadmill, somewhat expensive for what it offers. The only positive thing is that it folds by unscrewing some screws, which are also of poor to terrible quality. But it is difficult to transport due to its weight and size. If you have space for such a large and heavy treadmill, get something that doesn't become "cheese". Usually they offer more for the same money and have better performance.

Just received it, it's perfect for its price!
Beautiful, with minimal - normal noise, stable grip, sturdy construction, easy assembly and easy disassembly, can be easily stored, for example, under the bed...
totally worth it!! We'll see how durable it will be over time... I will come back with an update....

*UPDATE
2 years later, I have nothing different to say, it's excellent for its price and with proper lubrication at the right time, it will definitely last even longer! Its usage is frequent. I am completely satisfied!!!

I have it a little but apart from being beautiful, it is practical, ideal for those who have space issues and very stable. I weigh 85 kilos and easily reach 9 kilometers jogging...

Update 1
After using it for about a month and almost 4 times a week for half an hour each time for interval training ranging from 6 to 11 kilometers, I am personally fully satisfied in terms of price and performance.
It is quite stable... its noise is not loud, I weigh 84 kilos and wear soft shoes. I am not satisfied with the application, but this is not related to the treadmill. So I continue with a 5 out of 5 rating.
*ps I lubricate it every week for better motor maintenance

I was 87 kilograms (1.77m) and it helped me reach 70 in 4 months with a strict diet and effortless running!

Impressive appearance and convenient size for home, but not the best in terms of construction quality. It's not exactly quiet, as it can start creaking with any weight on it. The incline is NOT electric as stated and doesn't even exist. If not connected to a mobile/tablet, the only function is on/off and speed selection. When connected to the Gfit app, it offers many program options and saves your workout history in your profile.
