OK, I am sitting here, enjoying Letterman, when I see the usually "as a gyno" commercials. BLAH BLAH BLAH vaginal pH, almost sounded like they were going to say "Buy a DivaCup", but NO. There is a RePhresh PH balancing tampon. WTF? They want me to spend money on that? Don't even know what to think of it. I am not a cup pusher (your product choice is your decision), but if you have pH problems, a cup might be a better choice, not a tampon with who knows what in it.
