Review on Unlock the Fun and Learning with Teaser Puzzle's Interlocking Educational Puzzles by Jay Williams

The marble puzzle was my favorite! However, when I received my package, the objects were moving so much that the marble puzzle was completely unsolvable. The ball didn't spin and it was impossible to fix it. After playing with it for a while I was able to remove the ball completely (not the way a jigsaw puzzle works), but the ball was so messed up and poorly made that I had to hit it hard with a hammer to get it off . , and several times. After a little work to flatten the ball I heated and reshaped it the way it should be and now it works great! 3 stars because I had fun hitting the ball with a mallet. Otherwise I would give him two just for the other puzzles.
