Got this and a few other car-suitable games to give to some kids going on a long drive. I have enjoyed tangrams on my cel but it is easier to notice errors that way. Electronic versions allow for an outline you fill in. In a real version like this, you could use a big triangle where a small one should be, for instance, and not notice. But that is just the way things are, not a fault of this particular product.I like the design. Sturdy enough to last years, but small and light enough to not clutter your car much at all. It is easy to see your goal shape while working, the work area is roomy, and the magnets are strong enough to stay where you put them but not so strong it's hard to move them.Unlike traditional versions with wooden pieces in a storage frame, you can put this away in an instant, no need for sorting, which imho gives it an advantage over the wooden ones even at home.
