(Kerui name: Deeply independent, vivacious, quick and enterprising by nature.)
With good heft, finish and the Ultem tip the Kerui makes a great first impression out of the box. Admittedly, I was a bit confounded by the top tank design and grabbed the instructions to help wrap my brain around its function. The instructions are a bit lacking so I decided to just experiment.
The Kerui is comprised of seven separate parts all held together by o-ring friction. Other than the deck screws and 510 connector, the entire RDTA assembly has not a single thread. This may alarm folks worried about the tank inadvertently coming apart in their pocket or pack. I did lift my mod by the tank and it held, but carry the Kerui at your own risk.
The deck is a breeze to build and reminds a bit of the Hadaly deck with the clamps located on opposing sides of the deck, with a single screw securing each clamp. Loosen the knurled screws the two clamps pop up under spring tension, which is a nice touch and makes it simple to insert your coils leads underneath. Careful though: if you loosen the screws too far they can pop out and you may lose the tiny springs, and no spares are provided. The deck can still be used but the springs make it much easier.
Moving up from the deck, the chamber features two generous air slots on the bottom and two on top, which you can adjust to work in tandem or separately.
If using the Kerui as an RDA, the final piece is the top cap. In the RDTA mode, the tank attaches between the deck/chamber and the top cap. On the underside of the tank are two ports which allow juice to drip onto the deck. When it’s time to drip, hold the base of the Kerui with one hand, grab the top cap/tank with the other and turn the top portion clockwise until you see bubbles rise in the tank. When you are done, turn it back to close the juice ports and vape. The chamber is keyed to the deck to prevent movement wwhen you are turning the upper portion to drip.
