Installed the ULTRA-WH-PRO system in my house during a remodel. Our tap water was never "bad" by any means, but the difference now is great. Consistently fresh and clean taste, less water spots on plumbing fixtures (I opted for the descaler max). Skin is not as dry after showering. My girlfriend says she notices a difference with her skin and hair after showering at my house, less dry and doesn't need to moisturize whole body. Also, customer service is very responsive and friendly. It is a small company so I feel better supporting them, too.
