Yep, we obtained a bunch from lifevac, placed into each squads med bag, donated couple to our ambulance crews, and also put them in the school nurses office and lunchroom, as that is the most likely place a kid will choke.
The videos show them working. I tell the guys, if you have a choking victim that is too large to move or dofficult to perform the heimlich, then that is where this tool may be helpful. Never had to use it yet.
