    1st review

    Very effective stream, usually does the trick after a 2 second burst. It is small enough to not be intrusive on my duty belt, and packs a pretty good punch. The only downside is that the inmates who are repeatedly sprayed tend to build up a tolerance. Of course that's when the CN is applied.

    When I got sprayed for training in the military it didn't burn at first, but as soon as I took 5 steps I was on fire! And it got even worse when I hit the water, I couldn't breath and it felt like a million fire ants all over my face! It works great for calming down riots or stopping a resisting offender

    we used this in training, felt like I got hit with a fire ball. Caused my eyeballs to blister and fill with fluid, it was horrible. However, I like knowing it's on my belt. It's small enough not to be intrusive, and easy to use. Usually a short burst puts em down like cattle. Works like a dream.

    When in academy we got sprayed with this and WOW I hated it. I'd rather get tazed or kicked in the face haha, but I always opt for the taser over this because I know if some of this stuff gets on me it kicks my butt.

    I carry the MK III X2 and it is hot. Had some residue on my finger after testing a new can and wiped my face shortly after, thought I was on fire!

    my local gun shop sells many varients of this stuff, do you have to be legally qualified to carry this stuff or can you just buy it and use it if needed?

    As an OC instructor I have used this product on numerous recruits and in-service LEOs. It is also standard issue for my former agency. I always found it to be very effective when applied correctly and consider it a good step in the Use of Force Continuum.

    Ok but not as effective as alcohol base. Good points are that it can be used with EID type products. Bad... as not very effective with cell entry and nothing else.

    IWork for State Parole. Most of the "Offenders" I deal with were fist introduced to the product in the Penn. The sight of this canister takes the fight out of allot of them.

    An effective product, though sometimes you have to disengage and let it work on them first.

    I've used this product before the 360 version to be exact not the best stuff but when I moved up to the X2 with twice the amount of capsicum content much more effective and overall worth the use.
