"While it's true these cages are more expensive, one does get what one pays for. The quality of the metal is rather solid, and according to the manufacturer's label, built to their precise specification so I think they're trustworthy. The most inexpensive cages available have a coating on the cage bars that (MIGHT) contain lead or other toxic compounds. For finches, that's fine - it would take a lot for them to chew into the coating. I'd rather not take the risk and, yes, one often gets what one pays for.
I like how this cage has two droppings trays; one up top and the other at the bottom. The one up top can be removed when the bird plays outside the gym, or it can remain in to eliminate the risk of toys or food getting soiled.
The acrylic front is an interesting idea, but makes my conure think there's nothing there. I think a full cage would be better for hand-fed intelligent birds like conures. Worse, the protective plastic film was stuck to the edges of the metal and small remnants remain. Not a biggie.
Still, I got this on sale -- and for the price and its mobility (the wheels work on every surface from carpet to road tarmac), it's a good value."
