According to my daughter and SIL who live in Mexico, hookup was easy. You suspect unwanted biologicals/cysts/giardiasis etc. in the drinking water. The price was very good. Now I gave them a water test kit. They said it would take 2 days to see results. As to whether this device actually filters out unwanted viruses or bacteria, I can't comment on it until I'm told. So no 5 stars until there are results.
