Very pleased with this purchase. We connected two garlands and hung this over/around our front door in early December and set it on auto-program.  We only had to change the batteries once in ~2 months which was a pleasant surprise.  Will use again next winter holiday season

Pros:  Looks nice, easy to program (set it and forget it), held up well in winter weather and battery life totally reasonable
Con:  Battery compartment is very hard to fit batteries into.  we had to use a flat tool (knife) to get batteries out and getting them in wasn't any easier.  Making for a somewhat miserable experience when trying to change batteries in cold weather.
