I have had a fantastic time using my K5 Drinking Water Filtration System. The dealer came out and installed it and was right on time. He was very descriptive in the product, and gave me some information as to what I would need to do in case of a water issue. So far so good. No complaints. Kids love the water. My wife loves the water. When we travel, and have bottled water, my kids complain and say the water tastes terrible. We've had it now for almost 7 months and never a problem. I can't wait to get a water softener now from my local dealer to do the whole home. I would recommend Kinetico, and I would recommend a K5 drinking water system. Thanks Kinetico!
