Honestly, that top cage isn't as bad as I've seen.
The cage you purchased is great, that was the one I ordered when I switched from my Hexagon. (The Hex was too big!)
But for future reference...if you ever get more gliders and need additional cages I would highly recommend thelashop. I'll post a link for you....the cages I recommend are currently out of stock but they come back in every few months...then sell out...repeat.
I know approx. how much the cage you purchased costs...as I said, I bought that one about a year ago...I'm sure it's close to the same, and I'm telling you, I bought TWO from thelashop for LESS than I paid for this one and the cages are awesome.
I got 2 for a total of $233.00 > I personally paid $260 plus for the same one you just purchased thru EBAY.
Anyway, just thought you might like the info. in case you need a future purchase.

The second one in this pic is the one you just purchased...the last one (black) is the lashop cage. It is 1/2in. shorter but a 1/2in. wider.
