This is an absolute life or should I say skin saving item. I noticed the difference I water qualitythe second the water bit my skin. I haven't had dry or itchy skin since installingtjis in my shower. On top of that, it took less than 7 minutes to install and was beyond easy to do so. Thank u, thank u, thank u to the developers of this product. I never, ever would have guessed that it was so easy, inexpensive and fast to get soft water let alone find out the miraculous benefits of such. How did I live without this?! Itchy and dry, that's how, lol.
