We're happy with our heron. I will say that the picture and description led me to assume it would be more 3-D than it turned out to be. It consists essentially of two "cupped" halves joined together, so it looks three dimensional in profile, but when seen edge-on the illusion is diminished. Even so, with careful placement it is attractive, and the real heron hasn't come back so far.
UPDATE: Oct 2012, we had become lazy about moving the fake heron around, and one morning spied a real heron sneaking up on the pond. Don't know if it was sneaking because of the fake heron, or whether that's how they always approach water. But the lesson is learned-- move your heron from time to time!
