Although the paperweight isn't bad. Test Results: I cleaned as instructed, then placed a tube in 1 liter of Wally World mineral water for half an hour, then checked with a digital pH meter. No change (tested at 6.3 ph) Tested for an additional hour of use. Again no change. Tested with two tubes in a fresh 1 liter water bottle for two hours. Again no change. In fact, my 7.3 tap water is more alkaline than this. If you return it (it didn't work after all) they charge you a 50% restocking fee!
