Worth the money will buy again and again

Works as expected.

These did not work at all, they all turned the very same shade of light green, no color variation at all and I tested against a variety of liquids from water to orange juice to milk to coffee. The acidity levels never changed and test paper barely registered any color at all from the brown. Save your money.

Is this some kind of a joke?! The strips do nothing but get wet. I tested it with urine and other liquids and there was no change in color as expected. It just look like the strips got wet and that they’re made of some type of construction paper. I think Amazon should look into the validity of this product.

The media could not be loaded.  It doesn't work.
