It’s a great little bird bath for the price !! Holds about 2 Gallons !!! 
I witnessed small birds drinking from it the first day it was out ! It’s made from a resin material and pretty lightweight but looks lovely in my backyard !!  I filled the post, while assembling it, which was really easy.  I also put a rock on the base and small decorative rocks inside ! We have deer in the area so not only birds but deer may want a drink !  I love looking out at it through my kitchen window !!
