SimplexHealth pH Test Strips for Urine and Saliva (200 Test Strips) in resealable Container, Detailed Instructions and 30 Day pH Tracking Chart

First time I used this there was no colour change in the stick provided (think I was too acidic and just off the scale) the second time I could match to the colour's shown on the bottle as I'd started to eat more alkaline based food. This product does work well and will continue to purchase as it's so easy and quick to use once you get the hang of it. Super fast delivery on Prime and arrived well packaged as always.

These work fine and are easy to use though have no idea how accurate they are. Four stars just because I cannot be sure they are 100% accurate.

Seems to be very accurate. I have tested it with different types of mineral waters then with Soda-Bicarbonated water. It is also Confirmed my extremely acidic pH levels.In case you can not determine accurately the value of your test, try to move it under better lightning conditions so you can match the shades confidently. ;-)Comes with detailed instructions and suggestions.The test strips could be a bit longer OR the container vial should be shorter as it is a bit tricky sometimes to get the strips out.

found hard to read from colour to colour

Clear & simple instructions make this product the easiest to use. I am pleased with my purchase, feeling I made the right choice, with the Simplex brand. My package arrived quickly, and gave good protection for the products enclosed. Highly recommend Simplex as easiest brand to use, giving good results, too. I was able to show a class how to use these quickly, making job more simple, they all returned their results which will be studied next week. Thank you Simplex.

Really easy to use and very helpful

These strips really work & match up accurately to the pH chart provided. They are a must have if you want to make changes to diet & lifestyle to maintain a healthy alkaline body. It's amazing how quickly the body can be pushed into the acidic region (Which is not good) through consuming certain foods & beverages. Highly recommended.

Supplied in a functional container that allows the user to have all information at their finger tips. Clear information given and a good colour scale that help the user easily identify the correct pH of the sample. Relatively cheap by comparison of other similar products on Amazon.
