Super cool addition to your spooky decor!  Rare find and great Halloween treasure!  Works as it should with eyes lighting up red in center; spooky sounds; tombstone opens and shuts; has sensor that allows to work without pushing yellow button each time.  Has on/off switch at rear.  Takes 3 AA batteries; not included.  Did have some battery acid issues but able to clean and worked well during test run.  Thanks for looking and Happy Halloween!
