These are very well made and cute. But Ive had them for a while, and not one hummingbird uses them. I live in Arizona, and I always have hummingbirds at my other feeders. Its not the nector I make the same batches the same way for all my feeders. Ill try another location and update my review accordingly. My last attempt will be to put the glass pieces on a wall or table by themselves, and hope I dont get ants. Its a shame because these were really expensive. And, of course, I no longer have the packaging.
