Ultimately, it's a bit meh. It dissolves quite quickly in the water and then colours/I suppose disinfects the water for a while. But I haven't noticed any improvement regarding build-up or limescale from the water, and for similar money, I would rather recommend the Larrin WC blok Mountain Fresh or the Grohe block. Both work quite similarly, but mainly better, and if you cut them up, they'll last even longer. However, the test was clear: one whole block per cistern to observe the full effects. In this case, it was literally money flushed down the toilet.
Dissolves quickly and therefore gets to work fast
It dissolves far too quickly, so it doesn't last very long in the container.
The cleaning effect is virtually non-existent.

Well, don't buy it for the money: -)
They last a long, long time.
Removes limescale in the tank. The float hasn't jammed since I've been using it.

He'll make a blue lagoon in your toilet bowl, like the ocean in the Caribbean.
It's taking longer than you'd expect to create that blue lagoon. No problem 2-3 weeks at the frequency of an average Czech family.
If the flushing mechanism breaks during these 2-3 weeks and requires repair, count on having hands like Papa Smurf without gloves. And you can't really wash it.

I'm just using the first cube, after 10 days it's still working. So far, so good.

Nice blue water in the toilet bowl: ) Whether it also disinfects, I dare not guess.
Sometimes blue spots are left on the bowl, which bothers me quite a bit.

I use Geberit in the tank and satisfaction. But I don't throw in the whole block, but in quarters, it's enough and lasts longer. Original Geberit blocks cost much more and the result is comparable.
