The pump stopped working after 3 weeks. The pool never turned into the shape on the picture and we did make sure that the ground is flat, but it was ok . The pump is not working , that is the biggest issue

A very low-quality and durability product, Sunday joy and Monday sorrow. If it lasts 2 months, you will be lucky. I list the problems: (1) I set it up on a concrete yard with a slight slope. Unfortunately, even this slight slope creates stability issues. (2) Tiny pebbles (essentially grains of sand) that were not properly cleaned from the floor probably made holes in the bottom, and from the first day, it loses a lot of water. (3) The inflatable ring also loses air, and after a month, it needs to be inflated 2-3 times a day. From the beginning, it had a very strange shape when I inflated it, bulging in some areas. (4) The pool never took the shape of the photo; it has bulged a lot at the bottom, and now the walls have a very steep inward slope, while its circumference has increased by 10-15 centimeters all around. (5) The pump is weak, practically decorative. However, the cover and the net help me with cleaning as it is small in size. Chlorine tablets are essential; they do an excellent job. For next year, I will buy it again, without a pump though (I will use the existing one). Either this one or I might try the Bestway. Even for one season, I think 35-40 euros is okay; I just hope I got a defective piece and have fewer problems next year. Anyway, I say it again, I don't believe this type can last more than one summer.
Update summer 2024: I bought the pool again, without a pump since last year's worked just fine. The cats went crazy, and even though I sprayed anti-cat spray, they punctured it several times. However, it seems it was the water that intrigued them, as when I covered it, they didn't approach it. The patches held up for this year, but I don't know if they will last for next year or if I will need to buy a new pool. Anyway, for 30€, it's a good investment

So the pool was installed on the terrace. The package did not contain a base, so we put a rug and it worked fine. I chose this one because its weight is suitable for the terrace (I wanted to get a bigger one, but I realized that this size is perfect). The filter works fine. It just stops working when it gets clogged. So you take it out, clean it with a hose, and put it back in. We can't buy filters every now and then. Now let's talk about hygiene rules. Chemicals are definitely needed to maintain suitable and healthy water. I bought 3-in-1 tablets and they work great. You also need to get a test to check the water (pH and chlorine). As for the cover, although I bought it, I don't use it because when you remove it, the water gets too hot. IMPORTANT: The filter must work for 8 hours straight every day.

It is a paradise on earth where you can have a vacation at home, avoiding the hassle of the sea. The purchase was worth it and I wonder why I didn't get it much earlier.
