This is the sh*t

I am super-psyched! My obsession with water has reached new levels!
For a long time now I have enjoyed the posh office life-style by having a Poland Springs delivery service. Having a water-cooler is very conducive of proper hydration and an ease of mind: Greenfield is only known for it's overproduction in crazy. No offense, native borns. But cases in points.
This afternoon at my weekly Walgreens wander-about I found this tool on sale for $3.75. It is called "Z-TESTER™ Electronic Water Quality Tester", produced by the makers of ZERO00 WATER, For Water That's Only Water. I just noticed an MSRP $30.00 price tag print and am wondering if I should rush back and grab the last three.
It is a pale blue pregnancy test looking device with a smart navy cap that has a helpful pocket clasp, useful for the on-the-go tester. On one side is a digital reader and the other a litmus-like scale from 0 to 500+ of "total dissolved solids" or TDS. My tap read 70, 71 and that is considered Mountain Spring/Filtered Water. Which is great! Hard water is 200 and they say Average Tap Water is 200-400. Then I poured out the tap and filled it with water-cooler. It registered as 002! Not only is that wonderful but it verifies that it works. Now I will carry this with me everywhere.
