Unfortunately I have a friend who does... Its utterly useless, and every day I want to take the snake from him for husbandry reasons... BUT because he's 'friends' with the slimy exotics shop owner here who sells WC animals ridden with parasites and advertises them as CB he "knows better" than I do... Which is why is 3 year old male weighs 650g max and is a 1/3 the size of my female half his age.... Sorry rant over.
UV is not necessary for nocturnal animals and is typically only really provided for balls by people with no clue what they are doing.
