Well after using this R3.5 for a full day I can say that tomorrow I'll be breaking out another PTB. It worked ok for the first couple hours, but it's started getting dry and the flavor has dropped off considerably now. Of course I had a hickup with my ego that probably didn't help. Apparently the button stuck at one point. I took a hit that was ok, set it down for a minute came back and took a hit that was pure burnt. Shook it upside down for a second and it's back, but its still dry and the flavor is almost gone. I'll see what happens if it sits overnight. Thanks again Bad! Love all the tinkering.
