We are on two wooded acres in Central Texas.  I hung this outside about 80' from the back patio and had a fun time watching the bugs zip and zap for many months.  Then the music ended.  I emailed their support folks (3 year warranty!) and they said the main coil from China was faulty and they were experiencing many failures.  They notified me when the good parts were available, they repaired it, and I'm once again listening to the joyful sounds of dead bugs.  I recommend this zapper but you may want to call their QA people and ask them if the faulty coil problem has been resolved before ordering.
