After doing a great deal of research I decided to go with the Fox Labs pepper spray. 5.3 million SHU, 2%, this stuff will to the trick. I carry the smaller size one on my person as a first line of defense, instead of defaulting to my carry piece. I bought several more cans of the 5.3 spray for the wife, brother and sister-law, mom and dad. It’s a little extra piece of mind and Ballistic Deals always has the best price on this stuff. It’s a good product and I like the way the go-button has a spring loaded flapper safety. It keeps AD’s/ND’s from happening yet is does not impede rapid deployment.
