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!
