The COG MTL RTA is a mouth-to-lung RTA designed especially for builders who prefer nic salts or high nicotine vaping. It's the new collaboration between Wotofo and Suck My Mod, featuring a single coil set-up on a 22mm build deck with a 3mL tank resevoir.

HIGHLY DURABLE DRIP TIP THAT FITS COMFORTABLY BETWEEN LIPS - The COG is paired with a drip tip that is designed to condense the vapor for mouth-to-lung draws. Made of Delrin and sized in 510, it keeps heat down to a minimum while offering tremendous flavor.

AIR REACHING THE COIL IS KEY - Although the air hole on the base ring can be adjusted, traditional MTL RTA's take air from the base interior with one-size inlet to the coil, which actually is still not truly regulated airflow control. The COG, utilizing gear mechanism, has 5 different internal air inlets that accurately control the amount of air and path approaching to the coil, giving MTL users customized draws for real.

GEARED MECHANISM FOR FINE-TUNED AIRFLOW - The COG MTL RTA has an innovative gear mechanism for very precise air tuning. Simply twist the base to fine tune your perfect draw. As the base ring moves, the mechanism transmits the rotary motion to the internal gear, which works like a revolver cylinder, aligning 1 of the 5 inlets with the only passage that directs an accurate amount of air right underneath the coil.

UNVEILING VAPE IN TRANSPARENCY TREND - Transparency is very trendy these days; in life, society, and now in vaping. The COG MTL RTA is designed with creative transparency at the top and the bottom. See through the bottom, gears joining together, making the tank even cooler.
