    Lego Gears fun!
    4 Stars
    Lego Gears fun!
    The builds are fairly simple and good for young children.The spinner build is difficult to put tension on and flip the spinner with maximum spin. We replaced rubber band which broke and crank with Lego power functions m-motor and ir reciever. We later shortened the height and made the motor connection sturdier.
