difficult to ...
Difficult to clean because you have to open the entire front and fold it up, which then falls down on your head. If you don’t lock it, the rabbit can open the cage itself. You should have it on a table since you can’t clean it from above, but have to crawl inside yourself or remove the whole top part.
I’m sending it to recycling and buying another one—having a pet should be a pleasure, but this cage makes it a pain.
