Bests & Worsts Reviews from Amazon

I was sold like many others about the great water this unit produces. In fact it did as promised for shy of 2 months; water tester showed 0 TDS and flavor was great. After 50 filtrations we noticed a sour, acidic taste to the water (check the internet to discover why) .... it smelled fine. Now the TDS are at 100. Replacing the filter after 50 filtrations is cost prohibitive for me. Bottled water is cheaper and so is the reverse osmosis system I now have installed. Wish I could get my money back. Very misleading advertising. Will be a main topic this Thanksgiving dinner.
