They were great. Their customer service is really good. They got the things really quickly because I'm not in the area that they serviced and my dad is. They were kind of my eyes and ears and they took a look at his situation in his house and the space he had and the ease of use and they really made some really great recommendations that we ended up following up on and then they got everything installed and everything is looking really well. There isn't additional cost. We gone out thinking that they were going to install a reverse osmosis system that I had already purchased but it was a complicated system which they recognized right away when they went out that that wouldn't be a good system for him plus it was too big to install under the sink so we ended up getting a different system that is smaller and simpler for him to maintain. This was the first time that we used them and we would definitely call them back out again. I did not feel like they were trying to upsell us. They were trying to figure out how to make the current system work if we really wanted it but it just turned out that there is a better system that would have been more applicable to his situation and they were really open to being flexible and trying to figure out a way to solve the problem so their customer service was really good in the sense of recognizing what the needs are and I don't think a lot of companies are really good at that. The price was fair.. It definitely wasn't overpriced.
