An interesting design, but the size of the pressure cup concerns me- it is a combat dressing, which makes me think they are thinking a gunshot (oddly, non-exiting) or stab wound. For a larger laceration, is that going to have an added benefit? Or after reading the website, am I missing something.
Although with one of their "Blast" model in the kit as well, this wouldn't be as much a concern.
I guess any extra pressure you can apply on any part of a wound is good..
