Does not work,
Verified Purchase(What is this?)
This review is from: WMA 160 pH Indicator test Strips 1-14 Paper Litmus Tester Urine & Saliva (Kitchen & Home)
I have just received these and they do not work. I see on the reviews that one reviewer says they do not work for 12 hours - if so can this be included in the purchase detail!
