Pico and Hcigar vt75 nano both with the Wismec Amor Plus Tank that was slightly modified.
When i first bought tank i tried closing the airholes as it was way to airy for me but the vape would get rather harsh.
What i did was take a joyetech clr pin with its silicone insulator and it fits perfect into the wismec insulator.
Personally a great vape and coils are easliy rebuildable as they are a larger coil head than the clr but i do enjoy both and its nice to have options.
Vaped many tank fulls with no leakage anywhere a plus is they are super easy to refill from the top.
Shown on left is wismec coil head with clr pin installed with its silicone gasket next to a joyetech clr for size comparison, also shown are the 2 different pins 1 wismec pin and the clr pin.
