OsterRoaster Oven with Self-Basting Lid, 18 Quart, Black (CKSTRS18-BSB-W)

Does this Roaster Oven actually brown a turkey? Also can we make gravy from the drippings?

Can an external, wired thermometer be used with this roaster?

Has anyone gotten satisfaction for the dull finish on the pan after use?

Can it bake things as a real oven like cake or biscuit. How long does it take to bake these? Big thanks to all
