Very cute, bright lights - I was pleasantly surprised at how much coverage they provide, and especially like the "twinkly" mode which makes them look magical. They last a good amount of hours (I haven't paid enough attention but they go all evening). My only complaint is that the wiring is so finicky that I managed to tangle both sets even brand new out of the box... I have no idea how I'll manage to wind them back up and store them. But I enjoy their effect so much I'm only knocking off 1 star for that.
