I have been using the toilet bowl for about three months and I am satisfied. It is very beautiful and looks high quality. The flush is minimal (I think less than my old toilet) but it never leaves marks or dirt on the seat. I am writing this because previous reviews had made me anxious when I bought it. Of course, the specifications state that the water level should be <50cm, I have set it to about 46cm. Overall, it is a good toilet bowl that was a good purchase at the price I bought it for (~200€).
I am deducting one star because the connection mechanism to the base is partly plastic, I would prefer it to be metal.

Stay away. The toilet bowl gets dirty at the rim after each use, at the point where the water from the cistern reaches. A technician from the company came and informed me that the toilet bowl is functioning correctly. The explanation I received is that they understand the problem, but it probably doesn't suit me. I conclude that there is a design flaw, which makes the toilet bowl unsafe for hygiene reasons. I chose the rimless one, as they are considered superior in terms of hygiene. Even the simplest traditional technology is better. It will be replaced at the first opportunity. I do not recommend it to anyone.

Generally, it's not worth its money. I bought it for its affordability, as I had previously invested in other Italian or Vileroy & Boch products. The lid has a flaw that not even cheap Turkish ones have, and from the first week, the lid leaves stains that don't come off no matter what. At some point, I will replace them with something better. It also splashes a little with a matching brand toilet bowl.
