I read some things about the cage being hard to put together or pieces being bent or missing but I will say that I got my cage in 2 days and only one piece was bent which was easy fix with a couple love taps from a hammer. My rats absolutely love this cage and I will purchase another one in the future when I get the money because it is on the expensive side but worth every penny! Also it only took about 45 minutes to assemble with just me and my husband.
