It could be a guy thing, I do not know, but gadgets are just plain cool .. Spy Gadgets are even cooler. Granted, I bought the X-ray glasses, disappearing ink pen, and the telescope from the back of comic books when I was a child. Why? Because they are cool spy gadgets! I also grew up with James Bond, I did was 007 and had a license to kill (usually my brother). Movies and shows like James Bond and Get Smart were very popular, and the gadgets they were used, the fantasies of millions of viewers. Thanks to technology, dreams of yesterday are a reality today .. and the cool spy gadgets we used for a dream are very affordable.
