Don't underestimate them, they might not be as easy as you might think. But then again, if you are persistant enough, nothing is too difficult!
Once you have learned the puzzles you can enjoy teasing friends by taking it apart real fast and then rejoining. Now you can watch others struggle. Strong gage metal helps prevent your 'Hulk-Like" friends from bending this puzzle - no cheating please. Enjoy!
