Review on π Universal Paper Strips Measure by Jovitec by Patrick Matin
Supplied without instructions
They came without instructions. Not in the box, not on the case itself. Having never used these strips before, I'm not sure how much water to use or how much tape to use. Should I just dip a piece of tape in water or throw the whole piece in a jar? How long should I leave the tape submerged in water? I want to use it to test for alkaline water and I dropped it in a glass and it turned green while the pH drip solution I bought separately turned the same water blue in the other cup. I'm not sure if they work and it's frustrating that there are no instructions at all. Does the seller assume everyone knows how to use them?
