Seems to be very well constructed. My wife thinks it is too hard to arm but I have no problem with it. It should be hard to arm, in my opinion, in order for it to have good suction. It gives me peace of mind knowing that it is available should one of us begin choking, particularly if we are alone with no one to apply the Heimlich Maneuver. I believe this a better option than the Life Vac Anti-Choking Device which is highly advertised on TV.
