I recently picked this up for my lady. She's a server and I wanted her to have something to pack around with her after late nights at work till she can get her concealed weapons permit. I did quite a bit of research into non-lethal protection and this one was the best options I could find. The next best thing was several hundred dollars. At that price a small pistol would be preferred in my book. This little guy is lightweight and user friendly. Just push the safety tab through the trigger pull and squeeze. The pyrotechnic charge unleashes a fiery blast of fury at your attacker. It has two shots of concentrated oleoresin capsicum in a gooey mixture that leaves the barrel at 90 mph. The goo is nice because there won't be any aerosol pepper mixture left lingering in the air to possibly blow back in your face. The first shot fires from the bottom barrel, second from the top. The first shot seems to fire a little lower as you can see in some of the reviews online. Makes for a thoughtful gift and $40 isn't much for a little piece of mind. There are some review links below.
