Isn't this the cutest little thing you ever seen. [emoji4] Boreas V2 RTA It's a dual coil, the deck is a little strange to build on. It's not hard to build on, just strange. You unscrew the bottom of the tank and the deck pulls out from the bottom similar to a drop in coil. I ordered it for a Squid Industries Double Barrel that was supposed to arrive today but didn't. [emoji20] This is with the 2.5ml glass, it comes with an extension tube and a 5.0ml glass installed. Sitting on a SMOK Alien for size comparison.
