Anyone have a complete home reverse osmosis system installed?

As the title says, anyone have a complete home reverse osmosis system installed? If so what kind and are you happy with the investment?

I have APEC water system in my house - 2nd one I`ve purchased. Loved it enough in our last house to install another!

I had a Rainsoft system and never had a complaint about it.

Nah, not us...just two smallish RO systems for our drinking water (one for house, one in the shop). Only have filters/softeners for the rest of it.

Have the dispensers at work. It is good tasting water.
