It is nice, but its not quite "perfect" as there is no small trap door in the top for the cuckold to pop his head up through in order to perform clean up or urinal service or to simply provide oral sex to anyone desiring it.
I suppose that if this were too difficult to engineer into it, the least they should do is provide a remote controlled lock mechanism for the cage door so that the cuckold's wife could open the cage so her husband could come out to service her needs without requiring her to crawl out of the comfort of her bed just to let cucky out so he can perform his duty.
