API 645 Bird Bath Bowl with Tilt-to-Clean Deck Rail Mounting BracketIt would be a great birdbath if it were designed so that it can be mounted so as not to tilt over. I followed the directions to the letter, and it still wabbles all over the place. I even tried putting a brick under it to stablize it; it doesn't help. I will keep it because it's already on the deck, but barely. It seems others have had the same problem, I guess it all depends on the measurements of your deck railing or whatever you installing it to fit on. In my case, it doesn't work.Bought it thru Amazon.
