Yeah, I might need those. Some folks said the knob even gets hot to the touch after a while. I don't know if they're exaggerating. Anyway, I pulled the trigger on the Bifrost Uber and the Valhalla. I got the last Bifrost Uber on Amazon (yeah, I'm that guy). Probably won't get it until next week, but I'm excited! Going to call this an early birthday present since my birthday is next month too.
