A waist of time and money,

This review is from: More Bench-Tested Circuits: Innovative Designs for Surveillance and Countersurveillance Technicians (Paperback)
I would strongly suggest that the would be purchaser look else wear ! This book contains little of what the title suggests, and of that very little, most of the information is simplistic or out of date.
