I really, really wanted them to be awesome. We spent the money on real "magna tiles" but I was immediately disappointed. Too bad how weak they are. I have regular (non-tile) magformers as well as fake magformers. A Magna tile isn't nearly as strong as a Magformer (both real and fake). DO NOT SPEND YOUR MONEY. Their magnetic power is weak, so unless you're ok with just 2D (not 3D) shapes, you're ok with that. But they can't take it. I wish I could get my money back.
