"I wanted to get these old reel-to-reel tapes transfered before they deteriorated. Your company did a great job at preserving some of our family memories. My parents were very happy when I presented them with the CD's of the old recordings. After all these years, I get to hear my Dad when he was in Vietnam. This stuff is priceless. Thanks."
