wanted 10, got a 100 for same price. works perfectly for my need

I liked the product. It does work and shows you alkaline and acidic liquids accurately. I used it multiple times in class. Quantity is also sufficient. I will surely rebuy it.

Does the job.

not accurate.

Good

Nice idea but not accurately displaying the lower pH levels. I tested it on buffer solutions.

I bought them along with a digital PH tester to check the acidity of fermenting vegetables and I realize it is not really of any use. You can barely guess between 2 ph units (say between 4 and 6) and the color reference is pretty different from what the paper turns into. In turn they are only good for assessing very/moderate acidic - nearly neutral - very/moderate alkaline but not to guess a numeric value of the PH.
