Since 'M' arrived, it's become my absolute daily driver. My FF2 has been relegated to only two roles: if I want to have an indulgent, flavour-filled experience with a new strain, and, nightstand duty.
The former because the FF2 does produce substantially more flavourful vapour than the M. The flavours are more clear, more pronounced, and more nuanced than with the M.
The latter because on occasions when I wake up at 3AM with an anxiety attack, the last thing I want to be doing is messing with a torch! I can just pick up the FF2, take a nice hit of knockout meds, and get back to sleep in a few minutes, even in the dark.
Otherwise, the M has completely blown me away in so many ways.
It gives very decent vapour, and using it has a nice, methodical, almost ritualistic experience.
She is just incredibly efficient. I think this owes to how very evenly and thoroughly the ground flower is heated. The AVB is far more uniform than from any other vape I've tried. The combination of airflow and condensation results in wonderful extraction. The size of the oven is great for small doses. I can load this to work effectively with about 1/2 the bud that the FF2 needs.
Even moreso, I'm just endlessly impressed with how ingenious this device is. The excellent functionality and mechanical simplicity is simply beautiful.
ETA: The price of the M is also a wonderful thing. A device this great at a very attainable price puts the use of cannabis in a less harmful way well within reach of so many.
