We used it last weekend at the 24hr Enduro at SIR. Keith was on our team and brought it with him. I think the set at the hobby show is the set that we used. The nice part is that they plug into the aux port on the tire warmers so that you can still use the regular individual cups to warm the set on the car.
We used the cooker to warm a set of tires at each stop the tires were cooked with a coating of buggy grip@ 60c for approx 1hr. Nice consistent tires each and every stop.
