I bought this cage for my Syrian, the main reason being is I have the Furet XL for my rats and this has the same base size, so I can stack it on top.
I like how spacious it is, there is room for a large wheel and lots of toys. I keep the shelf for her food and water to go on.
The only thing I feel is missing is a front door as the only access to this cage is by lifting the lid, so you wouldn't be able to stack other cages on top.
There are attachments for tubes also, although I haven't put any on (they don't come with the cage)
