Pros: cheap, lightweight, with punch holes for rack nuts.
Punch holes are great, because many racks in this price range have built-in threads, which wear easily. Here, you can replace the (not included) nuts, which is the more durable, professional standard.
Cons: cheap, hence not very sturdy.
I wouldn't dare loading it with power amps. It's ok for a couple of synths or effect units. I wouldn't dare putting too much weight on the top of it either, especially when empty.
When I mounted my synths into it, the one at the top wouldn't fit because the rack was a fraction of a millimeter short. So I forced a little bit (because I'm that kind of guy), and now the whole frame is deformed. It's still squarish enough (still useful, not completely destroyed), but not as pretty as in the pictures.
Still a good compromise I suppose, since you can't really complain for that price.
