Used these for a pH lab in my science class and they worked just as I needed! Students tested household substances and these strips were accurate.

Works As Advertised
Strips are of a good length and uniform color. Tests with HCl and NaOH show both red and blue work well as advertised. Information on wrapper about how color change is initiated is a useful reminder for non-chemists. Product could be improved in two ways. In addition to the tight plastic cap, a small disc of desiccant in the cap or at the base would also help keep the strips dry. On the wrapper, a reminder that the color change can be reversed by adding a solution of the opposite pH would also be helpful.
