Great to have on hand to check for alkaline water
Honestly, I have nothing to compare this to as in other brands to check for alkaline water.  I use a Pur 3X purification filter pitcher and wanted to check for the alkaline level.  Many people are buying water systems and some can get very expensive.  This gauged my water in the Pur pitcher as an 8 for alkaline and I checked the water in a very expensive water system (not mentioning names) and it was about a 8.5 so I was glad to be able to keep a check on my water as being alkaline.  Gave me relief in not purchasing a very expensive system.
