I bought this years ago and did have a small problem so I called the number suggested and talked to
Jon himself. He was very nice, fixed the problem quickly, offered to answer any other questions, and
sent me extra supplies. I was very happy with this purchase. The "set-up" is great and the advice
(use, blocking, etc.) is invaluable. I was fairly new to I.T. at the time and still feel that this
video was all I ever needed. I can certainly recommend it.
