Found out that they do work well enough for me.
I didn't think that they worked because they were always showing a high acid level.  I heard that apple cider vinegar will make your pH more alkaline, and I found that it really does.  It works better than anything else I've tried.  I probably won't need to buy these again but will make apple cider vinegar a regular part of my daily diet.  These strips served their purpose for me.  The color of the results don't quite jive with the charts on the package but it's close enough to get the idea.
