I bought fourteen of these for people from 10 to thirty-something. I enjoyed picking the words and making up clues. I even tested my clues on neighbors. Everyone enjoyed the challenge of guessing and the product worked well, except for one that opened on "tharp" as well as the code word "ghost", but she was a good sport and kept going until she got the right word.
I love using these as gift card holders so the kids have to work a little to earn their booty.
