Finding a bottle opener can be hard around my house when we have friends over. I really like this one! When you open the bottle cap the magnet grabs the cap so it doesn’t just fall. This is such a cool feature and makes you think how did I not think of that and how have I lived my life without it! The magnets are neodymium magnets. It can used indoors or outdoors. The bottle opener will not rust. It looks nice too, it has a matted nickel finish. It’s easy to install, just secure it with the screws that are included. This bottle opener is durable and well made.
