A new reverse osmosis system for our house. We had just installed a new filtering system that claimed to be almost as good as an RO. and we paid over 200.00 for it, and it was terrible! The taste was not perfect like an RO, and my stainless steel cat fountain was almost ruined by the hard water coming through! So we paid another 200.00 and put in an RO, which I highly recommend. With Christmas looming I'm sure I'll be doing a lot more internet ordering.
