Unscrew the bottom of the tank like you are replacing the coil. Look up into the tube, the piece you pictured should go up in the tube with the small part up. The coil (atomizer) will butt up against the larger end of the piece, just like it is sitting in your last pic.

It's possible that the drop broke the coil in the atomizer or possibly something internal in the battery when you dropped it. As Tam said first thing to do is change the atomizer.

It looks to be the seal that goes at the top of the atomizer. I opened mine up,and that is what it looks like to me.

It the RTA new? Of so did you clean it before use? If not could be oils from manufacturing left on it, mixing with the juice.

Welcome to VT.

The coils come in 1.6 and 1.8 ohm, either will work just fine. I can't tell the difference between the two.

Never tried Nitto, but I got a set of General Grabber X3's on my 08 F250 this past spring. I am quite impressed. I use the truck for hauling firewood, usually out of areas that you need 4X4 to get in and out of. They perform great in muddy soft conditions, and are actually fairly quiet on the road. http://generaltire.com/tires/light-trucksuv/grabber-x3

1st piece of advise using a mech mod, read, learn and understand Ohms Law so you don't become a statistic. That IMHO is the 1st step in using a mech.

3-4 weeks on a coil is not too bad. TC is not for kanthall coils, which is what the Smok tanks use. Stick with wattage and read up on TC, you need Ti, SS, or Ni coils for TC.

What tank and coil are you using? From the info posted, you are using the stock Baby Beast tank. You should be in wattage mode as to my knowledge there are no temp control coils for that tank. I run .5 ohm coils around 20-25 watts. I believe you can download the manual from the Smok website for how to set it up. I don't have one, so I can't be much help on that. Good luck, hopefully someone who knows more about this mod will be along shortly.

Glad you got it solved!

Got a better pic? My only guess is a sheet of plastic mistakenly put there in the factory, if that's the case I'd remove it.

Yes it will. A couple wxtra glasses of water a day are necessary when vaping.

Using e-cigarettes is vaping.....

Yes you can. But before you dive in to a RDA, you will want to learn about Ohm's law, and get a meter to test your coils before you use them.
