great for the class room or plant pH control
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.

Seems to work well

Good value for pH references
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.

A must have for anyone who owns a Apera instruments pH pen
A must have if you must have your Apera PH pen calibrated to accurately tell you the pH of your water before and after nutrients have been added. I recommend this as a must have for anyone who uses an Apera instruments pH pen. Accurate and it calibrates quickly instructions are pretty basic.

Works and seems to be an accurate reference material.
My only gripe is that it smells very strongly of wintergreen. Your instrument will smell of wintergreen even after you rinse it, meaning something is left coating your sensitive and highly expensive ph meter. This doesn't seem to impact performance however. And other reference materials are not as fairly priced, so its a good buy. My bottles arrived leak-free and were packaged well. I would reccomend this product as long as you can stand the minty-fresh smell that hangs around on your instrument for several days. Atleast it smells fresh i guess!
