I finally have a house to put Christmas lights on but don't feel comfortable hanging them myself (hate ladders). I loved the idea of this and how simple it is to use. This projector is only snowfall, but you can change the speed it moves. I like the simplicity of it. It plugs in so there's no batteries needed. There's also a remote which makes it easy to operate from inside and you can set a timer so it will automatically shut off for you.
