    Wish you would include expiration of product on the package.

    Let's just say it was a yummy diet, but not a very healthy one.

    In some of these tests, i knew the ph accurately because i had previously measured them using a calibrated meter, and in others, all i knew was this should be very basic, or very acidic, or solution x should be more acidic/basic than solution y.

    They passed all my tests with flying colors-- even those that were designed to make the strips fail (as in, the strip won't get any more blue because the test solution is outside the testing range).

    No surprises, no questionable readings within the appropriate range for the strips.
