My son just turned two and has outgrown his peg puzzles, he still likes them but they no longer challenge him.  So I decided to by these for him as he would have 8 different puzzles that should challenge him.  I was right, they do give him a challenge, but he also can do them in a few minutes if I talk him thru it.  For example, I will always tell him when starting out to find all of the wheels and put them together first.  From a playing point of view this product should get 5 stars.

Why only 2 stars:

I've only had this set for about two weeks, already my son has broken two puzzle pieces and one of the boxes.  When he broke the box it resulted in a very sharp piece of wood, as well as a really sharp edge on the box.  I've fixed everything with wood glue, but its only been two weeks!  Furthermore, every time we do the puzzles, even if nothing breaks, I see a handful of little wood chips on the floor.  I must say that I'm very disappointed with the quality of this product, certainly not what I would expect from Melissa and Doug.

Next problem is the difficulty of putting these pieces together.  The pieces have a very tight fit, there is no room for error.  As a result the toughest part for my son is not figuring out where each piece goes, but getting the pieces to stay together.  The box tops also slide off very easily making it difficult for them to stay in place as my son puts the puzzle together.

Then of course there is the more practical issue of having 4 puzzles in one box.  My son turns the box over and I have four mixed up puzzles on the floor.

I know it says ages 3 and up, and I suppose that recommendation should be followed, but by the age of 3 my son will be bored with these 12 piece puzzles.
