I bought this cage to serve both as a sleep cage and a travel cage.  This cage is not intended to be used as a primary cage.  I have seen a lot of junk cages out there but this is not one of them.  The quality of this cage is excellent.  I love the snap together design with no screws or bolts to mess with.  And yes, it is just as sturdy (or more so) than being bolted together.  Has slide out bottom tray for cleaning.  Feeder cups are well thought out.  Comes with a couple of items to truly make this travel cage complete and ready to go.  I was so pleased with this brand and design that I bought a second one for our other parrot.  This cage is only suited for a bird up to an African Grey in size.  Any bigger than that and the bird will be cramped.  It is a travel cage not a primary cage.
