Being someone who likes to take things apart, and build things the eGo twist with smoktech pyrex tanks (uses the same replacement coils as the Kanger) was a step up from the gas station ecigs, and the cheapo plastic tanks I had before, and enough to get me to drop the smoking habit I had for almost 30 years of my life.
But...... Like I said I like to mod things, build things, take things apart, and redesign things. Doesn't matter what it is I have to mess with it, and mod it.
Didn't take me long before I was running mechanical mods, and rebuildable atty's.
WOW!
Now staying smoke free (for me personally) was a new adventure in modding my devices, trying different types of coils, wicking, and now even making my own juice (that's a whole hobby unto itself for me playing with flavors).
I have introduced a few of my (now ex-) smoker friends to ecigs, and even passed on a lot of my starter gear (eGo batteries, and tanks with replaceable store bought coils) to them since I wasn't using it anymore.
Some are natural tinkerer people like myself, and have expressed interest in making their own coils, and juice.
They take to Ohm's law with a smile on their face, and mixing juices like a Hogwart's potions master.
Others don't want to put forth the effort to do so, and maintain their equipment.
This group would rather just spend a few bucks on replacement coils, and store bought juice.
In the end it doesn't matter which group you fall into.
We are all in the 'I want to quit smoking' group, and know what suits our own personalities and schedules.
Run with what works for you.
Vape on.
