I got it for full size juice cans and it works well for that. The hole and opener tip are a little smaller than a nicer wooden handle one I remember from my childhood, but this simple metal tapper is sharp, works great, doesn't bend much at all, and seems durable. Of course the other side also opens beer bottles but that's not what I needed it for.
Watch my attached video review to see it in action on a large can of pineapple juice!
