The bar spacing looks quite large (designed for larger birds) which can and will cause problems over the years, all you need is one reckless wing to get through it (and it does happen alot in playtime etc in wide space cages) and bang, you have a very expensive and traumatic wing break on your hands.
So long as the cage has bar spacing under 1.75cm (utter max) you are good to go.
personally I don't like it cause the clear front takes away climbing space, and I can just picture in my mind a bird flying straight into the front of it to land on the perch when the front is closed.
Yeah I totally scrubbed the idea of this cage. I got him a traditional parrot cage with a play top. Its pretty large.. 23x32x37 (cage only) and of course he is out of it every second he can be. He hangs out on the play top and just goes back inside when he gets sleepy (its tooooo cute!)
Heres the one I got. Its about 20-25" off the floor and the top is almost too high for me to reach, so I think its about perfect. I also have a slightly larger (kinda old..) cage for outdoor use if I want him to catch some sunshine
