We got this set for our 4-year-old grandson and he loves it -- it occupies him for hours as he plays and builds his wonderful "creations," with the bonus that he's learning all about magnets and shapes. My husband is an engineer and has as much fun with them as our grandson does when they play together.
I bought a smaller version of this toy at Christmas to give to my grandson, he loved it so much, and played with it for hours on end that I bought the biggest version I could find. My grandson has a learning disorder, and it is difficult for him to do some things that other children do without a problem. This Geomag building set has him creating things that have taken us all by surprise, when he saw our surprise he developed more confidence, and that confidence has him taking on some greater challenges. This Geomag building set is a win win toy. This Geomag building set is shared with his sisters & brother, and everyone has a great time constructing something new. My only concern is that it has many small pieces, and being that he is the oldest (along with his twin sister) of 6 kids, My daughter & her husband have to watch that the baby doesn't get a hold of them.I highly recommend this toy and will continue to buy more sets to add to what my grandson has already.Thank you,
