The worst purchase. Whatever the previous speakers say. The toilet is also running and you can't adjust it to collect more water. The quantity of it is specific.

For no reason should this specific toilet bowl not be preferred, I see that the price has increased and that's the only thing missing... what the following comment says, the water splashes, it doesn't flush anything - it only has beauty. A thousand times better to have something much more expensive with the whole package!

While it may seem impressive and the mechanism works flawlessly, what one should look for when purchasing a toilet is its ability to flush solid waste with just one or two presses. Utter failure! The design of the toilet failed in production. While the system works forcefully, it did not balance the water flow inside the toilet, resulting in the phenomenon of a "washing machine." Everything swirls around with force, but nothing goes down the drain. At least not everything.
P.S. The plunger is necessary.
