Bests & Worsts Reviews from Amazon

This little unit works exactly as described. However, the potency of the hydrogen diminishes over time. I also purchased a hydrogen meter. Upon receipt, it tested at -288. It tested that for weeks. I stopped testing. Then about 3 months it tested at - 202. Still GOOD! I began monthly tests. in the 5th month, it was testing every day at -15. Almost 6 months of daily use it never tested below 0 again. Now at 9 months, it tests around +90. My .R.O. system tests the same. City water at my home tests +133. A friend half-hour drive has well water that tests at +235. SO, really good 5-month unit, making 2 servings daily. If you found my review helpful, please click the button, right over...there. THX.
