Really got to respect most of those experts
I don't really know how the show works backstage, they probably have some interactions with the items before they actually appear on the scenes to shoot them, maybe not, but you really got to respect the amount of knowledge people like Brett, Rebecca or Hall Patton have. They just know so much in their fields of work.
Brett and Rebecca seem to simply know everything about almost every item the guys put in front of them. It's amazing to hear them speak.
