It works really really good for a roast being carved (less overall area). Steaks get to be difficult because you not only have top and bottom of each, but then all the thin side area. Total speed really isn't much different than a pan or grill though. Just more of a workout.
I've found it to be a useful tool but definitely takes some planning. Pre-searing helps a ton with it. Speeds up the final sear.
Definitely not the same thick, crackling crust as throwing something on a grill or in a pan for awhile...but I don't get that when I throw things on for a 45 second sear after getting a perfect cook anyway.
Didn't bother with it last night - did some boneless skinless chicken breasts at 150, separately did a mushroom pan sauce for them, then pulled them out, quick dip in an egg, little flour/salt/pepper and browned em up in a pan. Light salad on the side. Our kids don't even know how well they eat. :biggrin:
