I have been using their products for a few years now. They have been curious, prompt, and I have no complaints. Any small problems have been handled with prompt business decorum. The reason I started buying their products was due to the ineffectiveness of prescriptions given to me by my physicians, which I have no more, at least them who prescribed the latest fad drugs. I was able to look up herbs that would help my problems and purchased them from PIPING ROCK with no problems to my health. ITS UP TO THE PERSON BUYING THEIR PRODUCTS TO TAKE RESPONSIBILITY AND DO YOUR REASURCH. And be aware of your OWN physical well- being. They are NOT Doctors and are only suppliers of herbs. By the way I spend Well more on these Herbs, than I did prescriptions, and have had better results, Thanks for being in business Piping Rock.
