Seal doesn’t hold to pull back from the throat. Concept is great but fails to hold seal/vacuum.
i'm sure it's fine. thank gosh of course i have NOT had to use it so i really can't properly evaluate it but it looks to be a good product!
Thankfully I haven’t had to use it, but it is well constructed and my son and I practiced using it. It’s simple enough for him to use if he’s ever alone and choking or switch out the mouthpieces to help me if I’m ever incapacitated. It’s reassuring to have one in the house, as prior to buying one, I had a choking scare while alone at home and it shook me up. This is well worth the peace of mind.
