I'm an avid birder and gardener, so I was pretty particular about what I wanted and looked a long time for a replacement for a broken painted cement birdbath.  I was glad to find one that I didn't have to store in the winter, and had a classic design without looking "plastic-y." It sets by a tree that has a white birdhouse, so I wanted white.  I filled the inside with broken cement from my last birdbath and placed it on a circular stepping stone that has a river rock embedded surface.  This makes it very stable.  I like that it's not too deep, the surface is easy to keep clean, and the birds love it.  The birds need water in the winter perhaps more than in the summer and this one is great with a heater .  It was easy to assemble and I can move it if I want to without much effort.  Looks beautiful among my flowers and other ornaments.  And no upkeep, unlike my cement one.  Love it, love it, love it!
