This is the cage review thread for the Jack 72:

I like the cage a lot and have had it for one of my Syrians (unfortunately she only lived in there a week). Some of the gaps at the top may need a cable tie to push where the sides meet the top closer and in addition to this you may need to do the same for a door, because some can be loose. You have to self assemble it as the cage bars fold flat and as recommended the catches for the level will need to be soaked in water for a little bit as otherwise they are stiff and may break.
As for a wheel, I took Biscuit's comfort wheel off the stand and made the gap in the wheel where it attaches bigger so it would fit over the bars comfortably:
Hope this helps!
