Hey there, I actually have the 2 out of the 3 Lola03 posted for you to look at. With owning the cages in her 1st and the 3rd link, I would have to say I like the first own much better even though it is smaller (but the same size to the one you are questioning). It is a easy assemble, very sturdy and all the doors have latches so you don't need any zip ties for the doors, which is a plus! It is home to my littlest boy... and hopefully a friend soon.
The 3 cage (5 level) is nice because of its size but has many downfalls. It is harder to assemble and the bar notches (not sure what to call them) have to be squeezed with a pliers to put the pieces together. which in turn makes it less stable or solid. Also if you do like to clean your cages fully (not just a wipe down)once in a while like I do, you will have to unbend the wires potentially causing them to break off. Lastly all 14 doors either have to be zip tied shut or latched with something.
