I totally love this bird cage and so does my grandson's cockatiel.  She can have fun playing with her hanging toys and move around from top and bottom.  She loves the play area on top and is up there every day.  The seed guards on the sides prevent the floor from getting all messed up with seeds.  The cage is so easy to move around and was easy to put together and I had to do it by myself as no one was around to help.  I am 68 and did it so anyone else could to.  She was a little overwhelmed with all the space she had so I put here old food and water dishes in also.  It just took a couple of days and she was singing and talking up a storm so happy with it all.
