My two and a half year old has been playing with this toy over three days now and he just loves it.  As he has figured out how to play with it on his own he has gained a sense of accomplishment and it is good for fine motor skills as well as learning consequences (if the gears don't mesh, they don't turn, etc.).  It is brightly colored, the sound can be annoying but no more annoying than most other toys.  I highly recommend this toy.
