One of these arrived for me this morning from Myepack, just chucked a pretty straight forward build in with 0.5mm Kanthal, 6 wraps ID 3mm giving 0.3 ohms, so easy to build on, i probably wouldn't ordinarily use this but i just wanted to see how easy it would be to get it in, taking it easy at 35 watts at the moment and the vapour and flavour is impressive.
