DF Speciality Paper pH Test Strips for Urine and Saliva (100) Strips Accurate and Reliable 4.5-9

Work as they should

Works well and does what its intended to do. Easy to use.

Bought to test the claims that drinking dilute apple cider vinegar and manuka honey will destroy tooth enamel, as many dentist claim. They worked as intended and reliably.And if you're interested, 2 table spoons of the vinegar and one of the honey, diluted in a mug of water, has the same ph as your average lemonade so is completely safe ;-)Slight annoyance, Amazon warehouse staff stuck their barcode over the scale you colour match to...

The delivery time was excellent but this came with no instructions whatsoever - I am a completely new user of these and have no idea of how to use them............?!? So not very useful to me at all:-(

Box is difficult to open but once opened is good. No instructions but pretty straight forward. I use saliva to test and it's easy to match the results. Recommend.

Excellent product, easy to use, precise measuring.

These strips are easy to use and have a wider range than some - I tried other paper that didn't change color - presumably because I was so out of the heathy range.

Great product, great price.
