Honestly, I was really skeptical when I saw the ad for this product. However, ended up ordering because it's not even expensive. I was more curious about the water pressure. Just received the Ecowater though and it did increase my water pressure. Also, I bought some tests for the water to see if it actually changed anything and it does. This product REALLY works! The chlorine from the water is gone, PH level got up, and no more fluoride! I would totally RECOMMEND IT!
