plugging through fasttech all im seeing for minis is the k500, which is a notoriously "meh" eroll clone. They didnt really understand what it tis that makes the eroll better that other autos they got the 3.7v, but the biggest deal was swiotch reliability (the switch air vent doesn't clog up and break) so its got the standard "battery dies after a week" think that killed all the other automatics.
I still believe that if someone made a really reliable auto of ANY type it would win.
The winner for me should be Eroll PCC Mega - with 3 slots, and eroll with a slightly bigger cartridge - 1ml, or something, just extend it a bit. Too bad it looks like a dream which will never come true.
I still have my PCC Mega and it's a great "to go" device. I rotate between 3 flavors, and it's great.
