Lidl did a hanging bbq like this a few years ago, it was the same sort of tripod/suspended grill (very big grill - about 60cm - but it also included a big round steel bbq base with 3 legs. It was utterly useless as a bbq as the grill tipped over if it wasnt evenly balanced with food, so if you took a sausage off one side, it tipped the other way and it all fell in the bbq
however, the bbq base is fantastic and has been my standard fire bowl base when car camping ever since. Wish they did it again, I think it was about a tenner and I'd happily pay that again just for another one of the bases.
