Maxwaterflow is where I got my rodi setup and I have used it for 3 years but no complaints. Very cheap too......I bought it off ebaycanada from them. Spectrapure and BRS both look much nicer than mine and mine does not have tds meters attached or pressure gauges attached but still produces 0ppm after DI......now RO is about 3 but the membrane is 2 years old.....I replace filters every six months. I would buy from Maxwaterflow again.....and well I have because I get all my filters from them lol.
