If I thought it was possible to find, I would show a video of 10+ people with knives walking right through OC. Pepper spray is like a pain compliance thing, do what I say or I'll burn your face off. It isn't going to stop an attacker if they want you.
What pepper sprays have you been hit (in the face/eyes) with?
What pepper sprays have you witnessed being used?
No, OC is not a guaranteed thing. Yes, you are correct, some people have a very high tolerance and are not obviously/adversely affected and, yes, you can fight through it. But boy will it drop an awful lot of people like a sack of potatoes. It is an excellent tool to have available. I always carry a bottle. But, like I said above, I also always carry a gun. However, a gun is lethal force...OC is not. If the guy has a knife I shoot him. But absent a weapon or other aggravating circumstances OC is outstanding as it is not lethal force. In fact it will not actually injure the person.
I'd like to see videos of guys going right through a quality pepper spray. By that I mean spitfire, fox, saber, etc.
How durable are strike bezels? When you hit a hard headed guy repeatedly will the light still function?
If you are hitting a guy in the head repeatedly with a strike bezel the light functioning is probably nothing to be concerned with at that point. What you are doing is likely to be considered lethal force and the guy is likely to be somewhat seriously injured. Whether or not your like works....who the hell cares, really? You probably won't even get it back anyway.
