Update:
Two years later and my son still loves these! They are super sturdy - he's never broken any of them even though he drops them and steps on them and smashes things into them fairly regularly. He got another set from one of his Aunts that he added to this set to that he can make bigger, more awesome things out of them. He still wants more!
--------------------------------------------------------------------------

My son loved playing with these at his daycare when he was three. Now he is almost five and I got them for him for Christmas, hoping he would still like them and I was not disappointed. He plays with them almost every day and comes up with the most creative things you can imagine from just a few different shapes. His only complaint is that there are not enough. I saw other people said that, but I could not afford to get the larger set. I will definitely be buying more MagnaTiles - they are fun, inspire creativity, and are sturdy enough to stand up to a 4 year old's abuse.
