Thought I'd bring this one up again...
I bought some Inferno Spray from Cold Steel the other day. I've always been impressed with their knives so I figured they wouldn't skimp on this spray either. I got two key ring sized and two 2 1/2 oz size (the maximum a civilian can own in California). The wife keeps her key ring size in her purse. She doesn't drive (long story) and walks and takes public transit all over town. Since she can't carry (Again, California here) a gun we decided to go for spray as an option. I'm also getting her some self defense training from my friend's wife, who's been training women's self defense for 14 years now. We keep the other key ring size handy in the truck and the other two larger sizes staged as appropriate.
Some of the reasons I bought this instead of other options:
Cold Steel's repuation for a high quality product
The liqufying foam (can't fling it off back at you)
The direct targeting of the spray foam (didn't seem like alot of splash contamination)
The easy soap and water clean up claims
The description (claims) of the ingredients and how they break down and attack the bad guy's systems.
Rob,
It would be cool if you could contact Lynn at Cold Steel and ask him to compare/demonstrate his product to what you have access to in a show. His claims on this product seem to make it a pretty good option to have in the toolbox.
