As with the Serpent SMM, Wotofo worked together with the reviewer Suck My Mod on the COG MTL RTA. The Wotofo COG MTL RTA has a compact design with 34mm height and only 22mm diameter. The filling volume is 3ml and thanks to the Top Filling the tank can be easily filled from the top. The COG MTL RTA has a few features that make it unique.
The tank and also the top cap are made of clear and robust PCTG, which gives it a unique look. If you take off the tank, the deck appears. This is designed for the use of single coils, accordingly it has two opposite posts. The posts do not have postholes, but are held in the so-called clamp style. Since the clamps are spring loaded, it is easy to attach the coil. Between the two posts is the air hole, which lets the fresh air flow directly from below onto the winding.
The Bottom Airflow is one of the features that make the Wotofo COG MTL RTA stand out. Because the Airflow was realized by a kind of gearwheel transmission, so you have 5 adjustable steps (0,8mm to 1,6mm). The other feature is the transparent base plate of the base, so that you can see the gearwheels and see how the airflow works. Of course the Wotofo COG MTL RTA can also be disassembled for cleaning. All in all Wotofo has launched a very interesting evaporator with the COG RTA.
Here is a video of Matt from SMM, where he explains the tank and the idea behind it nicely:
