While the speed cook function works as advertised, the proofing function is set at about 76 degrees - not terribly useful.  The technician said the temperature can be set anywhere from 75 to 90 degrees, and could not be changed.  When I commented that 76 degrees was about the same as proofing on the counter, he responded that "not everyone lives in Florida" - a very flippant response for a service person.
