I must ask this question of anyone with a V2 hopper. While the backend dial is smooth like glass, as @MoltenTiger and I have stated earlier, does it feel like it has a bit of "play" in it? Please allow me to explain... By "play", I mean a "catch" (as converse as these terms are, they both, together, describe the symptom). Consider a "notch" (T1 to T2, T2 to T3, etc, is "one notch"). If you swing the dial all the way in one direction, and then - just as you begin to head back in the other direction - within one notch's worth of movement, is there a slight 'bump' in the flow of that return movement? Pointedly, when I slowly and attentively twist the dial back and forth about 1-1/2 notches worth, I get this "play/catch" effect that is on each side of the twist. I do engineering stuff, and these kinds of things make me imagine that "until the catch", there is no actual shift in setting, no actual movement of the internal part(s) that "do the work" to change the Temp. I do hope this made sense to someone.
