To the one guy who felt short changed by Peter in the course of a telephone conversation, it would help us to understand your angst if you would say what the subject was and what was your question. Because in general, there is absolutely no other cartridge manufacturer who so readily reaches out to customers and has also become a major guru in the industry, other than Peter.. The only other company that even comes close is Lyra, with Jonathan carr as its spokesperson. You must have reached Peter on a very bad day or at a very bad moment, because I have found him to be unfailingly courteous and responsive. We are lucky to have him.
