How in the world is that even possible? What is your heatup time from 20c to 180c? That's impressive, but i've owned about 7 or 8 of these babies, and they all went downhill after about 30 hours or so. And when I say downhill, I mean the startup time started to become absurd in the neighbourhood of 3 mins and more. And maintaining temperature was a struggle...basically just SLOW SLOW SLOW. My usage would be 190/210. And I would charge it when it was still warm.
Guess the Crafty isn't right for a heavy user like me, same with the Grasshopper sadly, which is why replaced my Crafty/Mighty. Now I feel like i'm going backwards to the Solo 2, but what can ya do.
I've also been reading alot on reddit, and someone took a tour of the S&B facility or some shit, might be a rumour, but not much info was released other than S&B are working and admitted to something new, rumoured to be the Crafty 2. It doesn't seem impossible to me, as it's been their thorn more than the Mighty.
And even though i've owned more than a 1/2 dozen Crafty's and 1/2 dozen Mighty's, not a single one had to ever be RMA'ed, and I USE my devices hard... never broken plastic ribs or bowls or anything.
