Great product to test your drinking/spring/purified water with....
Great product. I've been wanting to test the spring, purified, and drinking water that I've been buying in stores only to find out that my tap water is better than most of them!! - who knew. Great tool to have....fyi: most of your Purified waters are acidic (yellowish).....you want blue (alkaline), that will be your spring water (at least the Walmart brand water - haa)
