Author: CordieRating: 5 out of 5 starsthis set is fabulous. excellent quality, instructions, etc. very cool for my mechanically-minded 7 1/2 year old son. a world apart from Lego mania.
Author: MomRating: 4 out of 5 starsWonderful toy for the builder in your life. My son is 7 and has an abnormal level of patience and persistence. Once my husband built the 1st project with him he was able to build a second on his own. The directions are VERY difficult but like anything, once you get the hang of the 'language' it becomes easier.
