Not sure why this has such great reviews. Pretty wonky and misaligned after putting it together, feels very cheap. Some of the wood split while putting in the screws. Also smells horrible.

The bottom tray is tricky to slide in, which will be a hassle for regular cleaning. The trays are not held up by any supports, and the top tray on mine is so misaligned that it is not safe for us. A rabbit standing on it would cause it to collapse. 

Overall I think it's going to work with some mods but it is not usable out of the box and I'm pretty disappointed.
