I hired Clearwater Systems Meadville, PA to have a reverse osmosis system installed in my kitchen. The installation itself was very efficient. The guys who did the work were professional and quick at installing the system. I would give them five out of five stars. However, there is a brushed-brass spigot we ordered quite a while back, and we're still waiting for it. We contacted them several times, and even the customer service guy who sold us the system said he's still waiting, as well. Overall though, it was a good experience.
