Please note: This product is designed for experienced users, and for those possessing an ohm reader or multimeter to test their coils on. This device requires a comprehensive understanding of the technicalities of vaping, along with knowledge of electronics and ohms law. We don’t advise any beginners to start rebuilding coils without speaking to a knowledgeable shop.

Additionally, we do not recommend using this kind of product with a mechanical mod of any kind. A rebuildable coil must be tested carefully on an ohms reader before it is used on a device. Not testing this properly may present a safety risk for the user, and no new coils should be used on an electronic vaping device until the coil is known to be safe.

Suck my mod (11 April 2017)

This little atty has been subjected to some pretty mixed reviews, so here's another one.

Cons:- fiddley to wick, fill, and adjust, small tank, (if you can get an hour out of this you're doing well),short drip tip.

On the other hand,

Pros:- absolutely stonking, for flavour, clouds.Get this right and it's fantastic! The " notch" coil supplied is over wicked, so YouTube what you need to know, there's a lot of support out there.

Hey, I'm a happy bunny.Just can't put the damn thing down ;-)

( You might like to know what I'm doing, Sigeli Fuchai 213, running at 21w, now using Digby's nasal clearing Moriyas Mix , twin airflow , omg, it does the job)
