I bought this for Operation Pine Plains 5 in Upstate NY, a mil-sim game of 21+ hours of continuous gameplay at the Ft. Drum MOUT training site, the past few games I have gone too I have seen various injuries at the site, from hand-burns from crappy smoke grenades burning through the sides to bleeding faces due to BB fire and the ever present heat related casualties.
I got this for the simple fact I wanted something small and something I could forget about. it's light, even loaded with your basic First aid kit (I have loaded it with more, a Stethoscope and BP cuff for the heat/fat guys) along with some gloves and a scrump pad. It all fits rather nicely.
Thankfully I didn't have to use it but for a scant few blood all over my face due to BB shots and nobody was seriously injured. I thought it would just stay on my vest, doing nothing, but when I was supposed to be given a medical bag for my vehicle for the fire department they ran out as 3 or 4 of us became EMTs at the same time. I now have this in my vehicle as a temporary replacement.
Since it fits my BP cuff and Stethoscope, and basic trama/bleeding control, it can easily be used as a first responder bag. Since the FD would be right behind me with the main bag anyways, I don't really need something too big.
If you're an EMT that wants to carry gear around easily on the airsoft field, with easy access, this is fantastic. The rip away works great, and the pack won't just magically fall off of the velcro. It's build well externally. and the internal contains all of my basic crap that I would need as a first responder
It is small, but I consider this a pro, as you can easily get yourself carried away with the "What if I need..." and end up carrying more medical equipment then you could ever hope to use. It makes you bring the essentials, which is all you need.
it's also 20 bucks. That's fantastically cheap for what you get.
I really don't have any. You have to have it in front of you if you expect to get it out though. It's not very backpack/back of the vest friendly, so it does compete with magazine molle space
