Well, in the review, I was supposed to be sprayed in the mouth. I assume it would produce a very similar effect to the one you described.
It's true that choice of spray depends on the situation because each type has their advantages and disadvantages. Foggers more resemble area weapons, and great if you need to leave a "cloud" behind. The disadvantage of foggers though, is that it can be carried by the wind. That's the strength of the stream, because it's concentrated. Disadvantage is that the user has to make it connect with the attacker. And of course, foam you've mentioned it's advs/disadvs.
You know what? I realized I wasn't clear enough in my review. My recommendation was made for most folks who are carrying it when they go out. I'm going to go and clarify that. Thanks.
