Every time the bottle opener touches a bottle cap it says, "Oh Yeah, Time For A Beer." And it says it with such enthusiasm that you can`t help but laugh. It`s not often you see something that is so functional and fun at the same time. No buttons to push, works by touching a metal bottle cap. Try it out on your friends. Great for parties and picnics. Also, makes a wonderful gift for any beer lover. Made of durable hard plastic. Batteries included.
