My name is Robert Campbell, I am around 40 years old. I like to drink the purist and coolest water possible for the least amount of money. I purchased this unit in March 2017 and it was expensive, but I am happy I purchased it. It has been two months and my electric bill is about 10 dollars lower and I do not have a bill at all, from the Bottled Water company that I used to get my water from. I tested that water that I was paying for with the TDS-EZ Digital PPM meter and it turns out that, while the bottled water tasted pretty good, it was still had a very high amount of total dissolved solids compared to the RO water filtered by this system.
