Some side bar discussions of the Premium, my comments are. The lid vent? why not on the top like the summit, like the ranch, like the old One Touch premium?
I am sure the reason for the way it opens is for stability, with two legs in back and one in front if it opened back, like the summit it would be back heavy and fall. What about really reinventing the thing, put two wheels on front, one on back and open back and not caddywampus style. Just thoughts. I LOVE, LOVE, LOVE the defuser and want one ASAP.
