At first I was excited. Everything looked good. After a few days, however, the shape of the pool has changed. The film is bulbous and he is no longer as high as at the beginning. He is also very sensitive. A rebellion on the edge can rapidly cause an overflow, which is not to stop children. Since then go fast times 1000 liters in the garden. So be careful. Overall, I find the process is not so great, but enough safe (for one or two summer) from.
