Before this purchase I had a lot of scale in toilets and some pipes. Part of the advertised function is that lime is converted to sediment and sent downstream. To be honest, I can't say anything about the formation of limescale, as I hired a house cleaning service shortly after the installation. They clean the toilets to keep plaque from forming. However, my sediment filter seems to be catching more sediment. So maybe it works, maybe not. It is difficult to judge a "negative" result. Installation was fairly easy, but I had to build a stand for the electronics to raise them off the floor. It didn't matter much. However, it is very important to pay attention to how you wrap the wire around the pipe and where you place it in your piping system.
