I have one. It does have a temp control dial on it, but it didn't do any good for me. Why? Because I turned it up all the way, put in 3 racks of baby backs and 8 hours later they still weren't done! I think the temp barely reached 200 and I haven't used it since. My advice is have your brother fire 'er up per the instruction manual and after about half an hour, check the grate temperature via a remote thermometer or an oven therm (he needs 225 at least). If his unit is like mine, that butt will never get done. Good luck.
