Kayfun Mini V3 Style RTA -  is one of the best one out there. The build quality is superb, the threading is smooth, and I’ve had absolutely no leaks whatsoever from using it.

It’s easy to do a single coil build in here with a 26g or 28g wire, but thicker wires like Clapton wires may be a challenge. The post deck is ok and definitely easier to build compared to the Kayfun V4.
I used the airflow exactly as it was, and I loved it. Adjusting the airflow can be a hassle, but you probably only need to do it once or twice anyway.

Features:

• 19mm diameter, 58mm height (with driptip)
• made of 316 stainless steel & glass
• top-fill tank with 2ml capacity
• adjustable liquid control and air control, with 4 air holes
• 510 threading connection with djustable center screw
