Overall, it is good and fits properly. The problem is that at the points where it is tied with the strings, the plastic starts to tear, as a result of which it needs replacement almost every year. There should be reinforcement at the edges.

Also, in the intense heat I do not cover the pool, because the cover acts like a heater and the water gets excessively warm.

Firs this cover pool is black not blue. Is just a simple piece of plastic. Does not protect. In a simple wind is not able to really cover the pool. Zero stars to the seller.

When there are winds, e.g. 3-4 Beaufort, and you want to cover the pool, a single knot as it is made to tighten around is not enough to prevent leaves, insects, or anything else from falling in. It loosens and gradually falls inward. And obviously, in stronger winds, it will end up elsewhere. The quality is good, but for the use we wanted, it did not satisfy us. Good for days without Beaufort/with calm.

Bad. It has holes on top that not only let dust and dirt in but also let water out, and it sinks no matter how well you have applied it.

Necessary protection for leaves and debris. It requires attention as it was cut due to mishandling. Greatly reduces pool cleaning.
