"I have never seen more responsive and knowledgeable tech support. I have been in this business since the 8088 processor and I have dealt with many incompetent (the norm) tech support. I don't know what you did differently but PLEASE keep it up.

"....your support is the best in the industry.
That is what makes your product!"
