I have a female Green Cheek and a male Black Cap Conure, with the divider in place and they seem quite thrilled with their new accommodations.  Expect to invest in new toys and perches to fill space.  My only complaint is as previously noted - instructions.  The tip offered by another poster that the tabs go inboard and up was very helpful and I had to switch backers on the cages with I discovered the extra tube on the one (to be used on the left side cage).  Otherwise, common sense worked wonderfully.  There was a hole that wasn't properly punched, but was fixable and I found one tiny spot of rust on the exterior that I oiled.

Pros: For what I paid, an excellent value.
Cons: The instructions suck.
