Bests & Worsts Reviews from Amazon

I just received these and they did not fit well at all. Had to force it on and to stay closed. I used it for the first time at bed time and soon after, I was awoke to the sound of what sounded like a gunshot next to me head! Turns out the lid on the soda had blown off with such force, it left a dent in the wall and had it been close to someone, would have have caused injury, no doubt! That makes this not only ineffective but down right dangerous. I don’t know if this has happened to others but I cannot recommend this product to anyone.
