I have been using these guys on and off for years. Once upon a time they were helpful and knowledgeable, not so any longer. They sell me water as RO/DI but when I tested it at home, its got phosphorus in it, which tells me they are too lazy to change out their own filter. They refuse to help carry the 5gal jugs anymore (once upon a time they did it happily). Add that to the fact that the people in store never seem to have the slightest idea what they are selling or why, and certainly not what for, and I have decided not to bother with them anymore.
If all you need is palatable drinking water, they are probably just fine. For anything else, I would urge you to take your business to some more knowledgeable professional company.
