I bought the pool for my granddaughter, she was to spend the holidays with us. After nearly 3 months of daily use, we discovered the pool as a plunge pool after a sauna. The water we have added means of a float every week a multifunction tablet. Prima quality until today. Against the small pump I can not say anything negative, the pump filter was cleaned every morning with a strong water jet. Have covered with a purchased cover the pool every evening. The upper air ring was unfortunately damaged after a short time. (Lost air). Leak could not be found, so every morning was announced pumps. Nevertheless, I am happy with the pool. buy me a new one next year. We live near a bathing beach, if we had bathed there every day, I could buy 10 pools.
