Unfortunately, after a very short time the button is broken (only went at certain pressure points) and a few days later the pump was in the bucket.
In addition, the design could be much better. Below the water is sucked in, but probably has no bath tub children let alone a completely straight wall. That is, it is always an angle and the water is thus injected back to the pump. Below would be a much more convenient hose and if necessary make the easy 2-3 cm long and 2-3 cm wide. As it stands now, there has unfortunately even if it works sometimes very limited practicality. Too bad, the idea is basically super! Maybe you should just consult parents in the design and insert into the Chinese production a minimum of Qualitätskontrolel.
Amazon, of course no ifs and buts taken it back. Nevertheless our daughter was sad that her toys was gone, again the same scrap but we did not buy.
