The instructions state to not have the face mask attached to the device while its stored. So, it would need to be attached once choking commences. I doubt many people (me included) will be in the best frame of mind to remove the face mask from it's packaging and assemble it to the device.
I purchased one for each of my kids as a Christmas present. What’s better than a life saving device for the ones you love.
Seems like it’s a good product, but I have not used it and hopefully I don’t need to use it but I like to have it on hand just in case thank you
