I bought this for my 11 year old son for Christmas and was a little disappointed with the contents of the box. The pamphlet is quite short - 12 tasks and some score sheets, but on the positive side you do get a stopwatch as well. Some of the tests are easy to perform eg. hiding a treat under a cup and seeing how long it takes for him to retrieve it. Others involve quite a bit of planning, for example, moving furniture around or making a cardboard contraption behind which a treat can be hidden. Overall, we had some fun, particularly with the treat-hiding tests, but there weren't as many activities in the pamphlet as I had expected. Good, but limited in its use.
