pH Test Strips for Urine & Saliva – 100 Easy-to-Use Strips for Fast, Accurate pH Testing at Home, Get Clear Acid-Alkaline Balance Results in Seconds, Perfect for Tracking Your Body's pH, 4.5-9.0 Range

Seem to work well, giving a consistent reading, but we have nothing to gage it against. So who knows.

Easy to use for testing urine Ph; the testing end is marked.

The color chart on the bottle does not accurately correspond to the actual colors on the test strips. Impossible to gauge pH precisely and requires some intuitive thinking. This seems to be true for other brands as well.

Good product

I use these to test the ph. in my mouth. As far as I can see they are helpful as I am trying to better understand how the ph. changes in my mouth and thus reflects on the condition of my teeth. I do not use it regularly, rather sporadically. I am also taking the "XyloBurst - Xylitol Mints | Sugar Free Breath Mints for Oral Health | Gluten Free, Vegan, Keto Friendly | Aspartame Free Mints | Peppermint | 200 Count Jar" mints in tandem on a regular basis- my teeth look more clean. So I recommend these strips to do what they say.

It works. But it doesn't explain what the top and bottom colors mean.

Es muy bueno hacerse una prueba diaria del ph para mejorar su salud

Very convenient and fast way to test. Enjoyed the value and of course reliability. Thanks.
