My adult son choked on French fries today while I was driving on the freeway. He couldn’t breathe and was very scared. I stopped the car immediately, took it out of the bag and used it on him. With 2 plunges, the French fries were out and he was breathing. It only took a matter of seconds to put together and use it. Because of this device, my son is alive! Thank god! It is definitely worth the money. I am going to buy more!
