Saw the scale on the outside of the bottle and could figure it out without even using them.So I didn't use them yet.

Now I can make several tests I need for science projects.

My vial of strips arrived with product stickers all over the outside of the vial...even covering the color markers that you use to interrupt the results. Removing the stickers has been a pain. I should have just returned the thing.

The color scale is easy to read.

I used these strips with the high school chemistry class I teach. They measured pH accurately for solutions I made of pH 0-3 and 11-14 (using HCl and NaOH), but tended to read right around pH 6-7 for anything else. Unfortunately, this made them unusable, as student results were wildly off.

Did not change color with tap water and lemon juice

These strips don't really work properly, see pictures: the three strips (top to bottom) are 5% vinegar, tap water, and baking soda. It's clear that water looks acidic and baking soda looks like water. Maybe a bad batch... but even so quality control is very poor. Dangerous to use.

The test strips I got do not work... They remain the same color regardless of what I am testing..
