We bought this for my 2 year old who loves to build and is obsessed with his magnet set. He likes building cars and trains. They are very well made and compatible with Magnatils and other branded tiles. Some people think the magnet isn't strong enough, but I find it's enough for small hands that wouldn't otherwise be able to take it apart when assembling it. They are very well made and can be played on again and again and sometimes even thrown across the living room. Highly recommended!
