I don't own one, but here's what I know about them... John Rogers manufactures his cages in the USA and each cage comes with a lifetime warranty against workmanship and rust. They drill all of their bars rather than weld (which apparently according to him and Mark Mann is the better, safer, stronger way to do it). They are all custom and hand built (the ones on their website are just "ideas" or templates for cages). They typically have a 12-16 week lead time on all of their cages. They use ceramic bowls. I got a price quote from them and they are quite pricey and I couldn't find anybody that actually owned a cage from them, though I had heard from a parrot behaviorist that some of her clients had them and they seemed very nice. I think that if I had asked for some references or could see somebody else's cage it would have really helped. They seem really top of the line. He calls them the "Ultimate Cage."
