Just had Big Iron install both a filter system and a RO system at my place. I hated the sulfer smell....its gone and the RO system is producing good drinking/cooking water. I haven't been home much since the install but the wife is happy with it. If you do get them to do an install do not pay the 450.00 for the "continious chlorine system" on your well. It is a fitting on your well cap with a plastic tube going down your well that "you" have to drop the tablets down (the chlorine tablets are required for the RO system). My wife arranged everything and when I saw the price for a fitting and a tube I lost it on the manager
and he removed it from the bill (it was already installed) and left it, acting like they did me a big favor leaving me with the 20.00 worth of parts. There were other issues with the way it was installed and some BS they tried to feed me but in the end the salesmen came back and made things right. So the system is good but not cheap, I looked at it that I plan on being there for a while and want decent water coming into my house. PM me if you would like more info.
