I have had one of these baths for many years and my budgies have enjoyed it. After going through a series of different cages, I put it into storage as it didn't fit my large cage, and I kind of forgot about it. Recently, I was on the hunt for a seed tidy feeder and was staggered at the prices of them...and then I remembered my JW bird bath, and decided to try that as a seed feeder. Well, it was a great idea because it works perfectly, no more seeds and husks all over my floor! Definitely recommend this product, have just purchased a second one!
