Saw their van on the road and called them because they advertise free analysis of water. Been looking to get a water system because lugging cases upon cases of bottled water up to my apartment was starting to become a real pain in the tush. The analysis was helpful as I was unaware there was so much stuff in my water. My water tasted funny and learned it was chlorine, turns out there are different ways to filter that stuff out. I ended up buying their osmosis purifier system because I wanted everything removed not just chlorine and particles. I almost bought their standard filtration system but decided to go with the osmosis because I figured worth investing considering what I've already spent over the years on bottled water. Their service was great and you can tell these guys are knowledgeable about water. I've already referred them to my neighbor. Overall very happy and best of all my water tastes better. I'm loving that I don't have to carry bottled water up to my apartment anymore.
