We Love this cage, and so do my 2 birds (parakeets). They were in a small cage together for a few years. I kept intending to get them a larger cage, but could not find the right one. Then I found Wayfair and this flight cage, which is the perfect solution. They are much happier now, as they have plenty of room to fly from perch to perch etc.  Also I love that it is on wheels, and has the shelf at the bottom. Once put together it's pretty sturdy. I am so happy I made this purchase, just wish I had found it sooner.
