Quick link to a post by Mr. Keating about counterfeit Stingers from China. As usual, quality counts, and it can cost more. I sometimes buy inexpensive training tools so that I can experiment with them (especially when I know that they're going to be abused or destroyed in the process). But I'm not afraid to spend on my carry gear, whether it's flashlights, batons, knives, holsters, or firearms. What's your health, safety, & well-being worth?
