Birdbath arrived well packed and in perfect condition. I have it on a tile slab to keep it balanced in a grassy area.  It withstood strong, windy storms without moving.  The top slides into grooves on the base, so it's not easy to empty the old water, but I've managed to keep it clean without any hassle.  After one full season, it's still good as new. I plan to bring it inside this winter.
