Excellent!
I'm very happy with seller and product.  It arrived early and works as advertised.  It's good info to know when you're trying to get healthy or stay healthy.  I highly recommend everyone balance their pH and tell others how to do it too because this topic is not readily available.  It's so simple.  We should be taught this subject in school but that would be bad for the economy since poor health is big business.
