Query: Not What Expected

I thought this would be a great addition to our local bar but I was wrong. I could tear a cap off with my teeth faster and better than this opener. It was very unreliable and wouldn't catch the cap everytime. And some bottles were like prying a weld off a post. And when that happens, you are stuck with an un-opened beer and the bottle opener stuck to the top until you finally get it off.A great novelty item that you could look at but not use. Don't show people you have one or you could embarass yourself trying to open a bottle.
