I just wanted to contact you to compliment your representative, Charles Kneifl. He has been very professional, ethical and helpful in being sure we understood your systems and that we were receiving the system that we needed. He even went out of his way to return when it was apparent that the initial system we expressed interest in was not going to fulfill our needs. Having been in business for over 30 years, I know that it is easy for customers to express dissatisfaction, but often appreciation goes unsaid. Mr. Kneifl is an excellent representative of your company and we hope he is appreciated by you.
