If you do, spring for the real deal. In fact, get a kick 2.
I have a
smok kick clone, and while it does the job, it's fussier than such a
device has a right to be. If it isn't seated just so it heats up. Keeping it seated just so is a pita, as the spring loaded side contact pushes it out of square with the interior of the tube.
It works ok for a proof of concept - I can enjoy 2 ohm cartos at 8-9 watts on my mech, but the cheap clone is just that - cheap.
