Entertaining
Bought for my Great Nephew, but kept the rest of the family entertained too trying to solve it. Made of wood so more sustainable than plastic which is a bonus.

Nice Present
A bit of form over function.Once it's done it's done and the value lies in how long it takes - in this case took a while for the 11 yr old who it was given to to crack it, but the presentation's great, so was a good present in all...
