Daily Vaper: OBS Engine Nano RTA Tank Review
The OBS Engine Nano RTA is 25mm in diameter and features 5.3ml e-juice capacity. It has a top filling design and an unorthodox side air flow adjuster. Usually air flows are found on the bottom of tanks. This RTA comes with a spare glass tube and an accessory bag. You have the choice of black or silver.
The video reviewer shows you how to build the Engine Nano RTA properly. Also, he says it is a single coil RTA. It comes with just 1 coil with no option to build a dual coil. During the video review he states that everything about this RTA is easy, and that it is very hard to find a downside with it. This RTA has large juice capacity, the build deck is simple to operate, and wicking is easy. It is leak proof and the flavor is great. Other positives include side air flow, top fill, and 510 drip tip. The vapor production is large even at low wattages, and it preserves juice.
