Simply place Decapitator over the top of your bottle and press down. The cap will hang on to the magnet built inside the Decapitator, so you can easily grab it and dispose of it. No flailing. No failing. Just place, press, remove and boom. Bottle's open. Cap is trash.
I purchased for four different family members and everyone loves them. Now their friends expressed how neat they are that I purchased for my Son-in-law to give to his friends for Christmas. Sturdy, excellent quality and everyone loves them!
