Well those kits don't look like anything. I mean they sound impresive and all but there is nothing in these packs you wouldn't be able to put together for $15. I mean if this had to be a trauma repsonse bag it is missing splints and cpr equipment, as a personal first aid kit you still have to add extra things to it Elastic bandages have really no place in the first aid since their elasticity can turn against you (either making something too tight or they can go loose on you). They are used in post first aid care. Petro burn sheets are on the controversial side since a lot of docs hate the fact that they have to clean up the burn from the jelly stuff. And I wouldn't see a need to apply the burn sheet to anyone unless they have third degree burn which happens but there are better products out there to help such patient. Trauma/Pressure dressing with velcro? When u need pressure dressing that usually involves bleeding and velcro doesn't really perform well when wet so there goes your pressure idea. On the positive side I really like the bag that fits on your leg. I wouldn't buy it unless you planning to heavly modify the contest which almost mean starting from scratches. I think that with couple of trauma dressings, med tape and some triangular bandages you will do better than with half the stuff they give you in that kit. But that's me.
