I am still using my Istick40TCW with the 10ml XTank 4.0 w/ .6ohm coils, have been for the last year and a half.
It is the perfect medium for me. It is small and has both battery and juice capacity to last all day.

So I am curious has any new tech come out in the last year and a half or so that I should know about?
I haven't been keeping up.

Yep. I am using a Smok Alien 220w off of two 18650 batteries with my old Smok TFV4 Tank. Getting hard to find coils for a good price. Typically .2-.6 ohm coils. And my Smok Alien is out of date yet is small and for the size is heavy. I replaced my Smok X-Cube. The Alien will do TC with all types of TC wires. Although personally do not like TC.

Alot has came out in the last year, hell, alot has came out in the last month.  They are rolling out stuff faster and faster.

I am running an alien also.

The only good thing about so much stuff coming out so fast is the price drops fast also.  I picked up a smok x-cube mini 75 w for 30 bucks today and a moonshot nano rta.

The only thing new out right now that is catching my eye is the voopoo drag.

Some of the new mesh coil setups look interesting but I am waiting for that to develop a little.

O yea and the 20700 battery mods are starting to catch on.

Yeah that mesh shit looks interesting. At least would be hard to burn the cotton if it is done right.

O yea, Innokin is coming out with a new tank that attaches to an rda. I think thru the sqonk pin that turns it into and rta.
