My Son Loves the way this was crafted. He set it out in the common area of his house to display and has lots of fun puzzling his roommates. It's just beautifully designed and fun to play.
Men can be hard to buy for. This was a great gift because it looked attractive just sitting out, like a piece of decor, but also gave him things to fiddle with in idle moments -- particularly useful, as he was trying to quit smoking.
My dad and I always get either other little trinkets for problem-solving gifts so I decided to get this for him for Christmas. He LOVED it! We bring it out every holiday and try to do the puzzles together.
