Bests & Worsts Reviews from Amazon

I bought this TDS meter thinking it would measure the Trump Derangement Syndrome level of the people I meet, only to discover that it actually only measures the PPM of the dissolved solids in water. So, (short story, long) I decided to not return it, and discovered that I didn't need to put new filters on my RO system because the PPM of the water it is putting out is only about 54PPM. Saved me some money, although I'm still confused as to whether or not my neighbors are sufferring from Trump Derangement Syndrome (all except for the guy directly across from me who has a Trump/Pence 2020 sign in his front yard). "Live and learn", seems to be the moral of this fractured fairy tale.
