Some plants need specific pH water to thrive. I use this to balance the number to where I want. ofcourse youll want to be in the lower ranges but they work great. Containers are well built and dont leak. I checked the pH with some strips and the levels were bang on. I thought for the price it was worth it.

These are the go-to reference solutions for testing the acid levels in wine. This brand has a 2-year expiration date. The coloration of these references makes it easy to not mix them up.

Works fine but package had been used or damaged in shipping because 7.00pH bottle was missing 20% volume and tested off on my already calibrated pH meter.
