It's about such a battery:

My husband has already replaced this head twice. Recently he bought a better and more expensive one, and for me it still doesn't move lightly and smoothly enough. It is difficult to turn on the water gently and precisely regulate its flow. I do not know if they are just like that and you have to accept it, or if you can buy a really good quality head that will move smoothly and lightly.
