clock was perfect for where i wanted to see the time.  simple battery placement and one nail to hang, a little adjusting when hanging to get the 6 and 12 perfectly lined up and it has been keeping good time.  it runs quietly which is a great feature because it is in our bedroom.  other reviews say it is flimsy, but we have other clocks with large hands and they cannot be heavy or it would not be able to go around  correctly.
