The whole lid starts shaking, I put glue and fixed it perfectly, after 2 times unscrew the top lid for some reason. I can't find a way to fix it

Worst quality of construction. The lid mechanism is of child specifications. No matter how carefully you install it, the lid starts to shake in 2-3 days. Screwing/unscrewing again and again.
Also, the toilet tank loses 5-6 liters/hour from the sealing rubber. Such a waste of money.

NOT value for money.
The mechanism for placing the lid (with a hinge) is problematic. The whole lid moves, risking damage.
I bought it from an official representative who initially blamed the plumber who installed the toilet.
But when I forced him to unscrew the lid of his showroom toilet and reposition it, his own lid broke. Even he admitted the flaw in the company's design.
The spare part costs 30 euros...

I don't know why my friend didn't like it, but it's excellent. The flushing technology and the quality of the porcelain are incredible.
The toilet bowl is short, which is strange at first, but it has the right height recommended for its use and it is very helpful in practice.
The sitting area is wide and flat, which makes it very comfortable.
The Aquablade technology is unique! Google it to see videos.
It cleans incredibly well, absorbs everything, and because of the better quality porcelain, you will forget about the brush!
You will also forget about chlorine (as the advertisement says) because due to its design, it doesn't hold any residue or stains!
At first, the tank may seem small, but when you need to use it, you will understand how well it cleans with such water efficiency.
Also, during the filling process, it is completely silent, thanks to a technology it includes.
It deserves 5 stars and even more.

Unfortunately, I made a mistake. No comparison to the old models of ideal standard. If you want an ideal standard like the ones we used to install in the past and lasted 30 years without clogging and having issues, you need to search for the old models that have been discontinued.
