I have one but quit using it when started using 3-2-1 method.
I prefer to lay mine flat so the meat side can better stew in the tasty stuff I add to the wrap.
Using the supplied top tray I can get three full racks of St. Lois spares flat on my Akorn.....where I could get 5 racks using the rib stand, however the 5th rack had to be cut in half with the 1/2 slabs on the outer positions.
I'm sure it'd work with foil, but I prefer flat.
