Review: Cheaper than the powder & just as accurate - I switched to these from the Hach powder. Still use my Hach color dial. Very satisfied as I take readings often a couple of times a day if I'm adjusting the level and this stuff is way cheaper than the powder packets.

### ⭐⭐⭐⭐⭐ Great Price
*by G***C on December 18, 2019*

This was the best deal I have found online...much cheaper than what I paid ordering from a magazine. The drops were good for almost a year and I've experienced no problems with the readings being inaccurate.
