Unfortunately, a defective batch has been released which, when you install it, loses the spout at the point where it screws on as soon as you open it. No matter how much you tighten it, the problem remains. I threw away two in one afternoon with many trips and a lot of frustration.
In the end, we installed a battery from another brand and everything was fine!

Good battery, just need to add a gasket to its spirals for the screwing into the switches (sockets) during the connection.

I bought two. One of them didn't close while I was lowering the handle. The store replaced it for me. The other one is okay so far...

I bought it, I installed it, it leaked immediately.
With a workaround, it works fine now.
I wouldn't recommend it

It makes a very annoying noise when using it. So intense that it can be heard even in the bathroom through the pipes. I do not recommend buying it. You get what you pay for...

It came broken!!! It's leaking water from the neck!! I sealed the crack with silicone until the new one arrives! Give a few more euros to get a better quality one!
