Your memory is better than mine. I didn’t even remember they take flat tops. You’re correct about how careful they were but that’s what made them so great. Essentially indestructible and their machining - butter is rough compared to their craftsmanship and how smooth their end caps are. Simply amazing stuff.
I vaguely remember some upgrade program they had - was that for the provari classics? Or maybe I’m just completely mistaken.
I know they did a P3 upgrade thingie (I forget the wattage numbers, maybe 20w to 30w?), and THOUGHT they offered it for the Radius too, but I trust GG's memory better than my own, so...
I think that was it, but again, I'm not 100% certain of it (or ANYTHING).
