Bought this for our 2.5 year old daughter for Christmas and she loves it! Will sit down with mummy or daddy for a good half an hour to complete all 6 puzzles. Although she still needs help to complete it I don't think it'll be too long until she can do it herself. Good toy for developing the concept of shapes/cubes without getting too mathematical! The only slight annoyance is that the completed pictures are displayed on the back of the tray so you can't refer to them while you're completing each picture (unless you did it outside of the tray). It seems very robust, the pictures are well stuck down on each block - will probably wear a bit on the edges and corners eventually but will take a lot of use before that point! As always a very good quality, reasonably priced toy from Melissa and Doug.
