Good for the simpler purposes
Very easy to use and shows result instantly.<br /><br />The only thing is I do not think it is sensitive enough for my testing purpose.<br />I use it to test the different water I get from different water specialty stores in my city.  They all declare to have very different alkaline levels, from &#34;just filtered&#34; (which should be just nutural, and to enhanced to 9.5+, which is very high in alkaline level), and this test strip doesn't tell the difference at all.<br />On another side, maybe those water stores are not telling the difference (they charge from 15 cents a gallon to $1.50 a gallon so I think the differences should be very significant.)<br />I am looking for some other alternative solutions to test the water alkaline levels.<br /><br />If you do not care to much about the exact reading, just simply test if something is acidic or alkaline, this product will be perfect for you! :-)
