Its not bad for a 2nd cage or a cage that you can transport. It looks a little flimsy (although my parrot couldn't escape nor did he damage the cage). The locking mechanism is very annoying. You have to use a small metal rod to poke through the lock. And if you loose the metal rod, you won't have a lock. The wheel frame is ok, it does the job and you can move the cage around, but don't think you'll be able to wheel it around a lot. 

I use it as a sun cage or transport cage for my conure so it works fine. I wouldn't use it as my primary cage.
