I've got 1 on the go already. Used 0.5 that came with it, 1 air hole and 7w on the cloupor mini. It's good but hot. Normally I don't sub ohm so maybe that's it. But impressed with the build of it.
With the cloupor mini you won't be able to get 7w from a 0.5ohm occ coil. If the chip can't step down enough the ohms will flash when you fire. It doesn't have step down or pwm so it'll just fire at its minimum which is 3.6v I think. With those occ coils I think you can get down as low as 18-20w if I recall but no lower. Just look for the ohms flashing.
No wonder it was hot if you had it at 20w with the smallest air hole.
FT are fine for batteries I think. I've had vtc5s from them and they took nearly 2 months to arrive but were definitely genuine.
