Title: fun but fragile
Review: The product seems to be well designed from an educational point of view - my daughter (almost turned 8) assembled it with no help what-so-ever. However, winding it up to much (even actually not that much) causes it to (a) literally blow apart from stress and (b) strip part of the main spring gear. Stripping the gear makes the toy useless. A new manufacturing run either with a redesign to lower the stress or with an improvement of the strength of parts would make this toy into an award winner.
