The magnetic feature works well and the foam on the outside makes the pieces lightweight. My kids are 3 & 5 and have enjoyed playing with these since they received them for Christmas. They have built a variety of things including rocket ships and robots. The only β€œflaw” I can point out is the price point. I consider these pretty pricey for building blocks and for the price I would have expected that there would be more pieces to build with. Review: Love! - Favorite toys for our kids!
