I've had One for about a month now, and its been good to me. Really like it with my Goblin mini, and the single 18650 configuration, great on the go setup.
For the "piece of junk" I've heard it called, thus far mine has been fine.
My only real complaint is they used the .5A evolv charging board instead of the newer 1A charging board. I doubt the 1A board was available when they were designing the mod, possibly before production, but at that point it was probably too late.
