Boy are you lucky to have Dr. Clark's brother to talk to in your own town. I buy my vitamins ... from them, too. You are going to love your zappicator when you get one. I put everything that I eat or drink on it for 5 to 10 minutes. And it is portable.
I found another good use for it. I put my down pillows in a plastic bag, squeeze out the air, and zap for 20 minutes. It kills mites!
