Accurate pH Test Strips for Urine, Saliva, Water and Fermentation - Food Grade Lye Compatible(pH 0~14)，100 Strips

Works as described. Compared with another brand of pH strips and they had nearly identical results. Will definitely purchase these again!

Box diificult to open without spilling the strips.

These strips did not work but I cannot find it in myself to return them, as I have already used about 10 strips. They seem really old and outdated. Maybe im using them wrong? I honestly cant see how someone would use something so simple incorrectly, but perhaps I am. Maybe there is another solution I dip them in before my test sample? I just couldnt figure it out. If I find a way to make the product work correctly, I will change my rating to what is appropriate.

I have been using this product for quite some time and I'm very pleased with it.

No instructions, no guide to know what im looking for. Complete waste of money.

No good

nice precise reading

EXCELLENT PRODUCT
