We bought this for Christmas 2015 - It arrived about a day before the estimated arrival date which was nice!  It came with its own air pump and has lights so you don't have to worry about using a spotlight to show it off at night.  It also came with plastic stakes + anchor lines that you can use to secure it to the ground -- overall pleased with this purchase and it looks great from the street 

Pros: I've seen other Nativity scene inflatables from home improvement stores with similar stats (size, lights) that cost more than we paid for this so the pricing was great!
