I bought a Czech azuro 4,6 circle pool from them, ordered it along with the installation, the manager immediately offered to take extras to it, but I decided to consult with the installer during installation, which of the extras really needed and was not mistaken. In 2 days, it was repaired and launched for me, Alexander (the installer) answered in detail all the questions while the water was being collected, what really needs to be purchased, how and what chemicals to use and take care of the pool. Yes, it is not realistic to remember all the instructions at once, but Alexander is always in touch and has helped many times with good advice on the phone. I am happy with the pool, finally it is not necessary to disassemble and assemble every season.
