Cute tiny little lights! Having to deal with batteries is a pain though! They take AA at least, unlike some other light strings I have ordered from wayfair, which take those crazy disc type batteries that last for like 5 minutes! The AA last for a lot longer, but I'd still prefer a plug in set of string lights as I tend to want to keep them on all the time in my displays. These are ok of you only want to use them occasionally for short periods and can't accommodate a plug.
