Packaged well, and easy to assemble (some may find it difficult to assemble alone, may need another set of hands). The construction of the product is very nice. For some reason one leg seemed shorter than the other three during assembly but once the whole thing was assembled it leveled out, I'm not sure what that was about. I did have to fix a small piece - the wire was bent where the cage door touches the front panel, it looked like it had been bent during the packing process (not a defect). Other than that, the whole cage looks amazing and it's HUGE, which is why we got it. Purchased for one adult rat, going to get baby rats to keep him company so we needed the extra sq footage for more ratties. I definitely would not purchase this product for hamsters or anything smaller than a fancy rat, there are places in the cage that could become problematic for smaller mammals or pets. I would not put anything larger than a ferret in it. Also, keep in mind the bottom is wire, this is not a tray bottom cage. Hope this review helps, we spent a week looking at cages before we decided on this one. This cage is probably the best cage I've ever purchased and I've been buying small pet cages for over 20 years.
