Yes, Gaia squonking RDTA but can be used with a solid pin and then can be filled using the hole on top of the deck, when squonking you plug the fill hole with supplied screw.
Useful to see when to squonk and deck is good size with Velocity style posts and airflows are Velocity style also. Dual coil, will handle in my experience down to 0.11 and up to 80W heat-wise.
Easy to build on, easy to wick and easy to fill the juice holes with wick ends so should never leak.
Proprietary drip tip (larger than 810) but comes with standard 510 tip adapter. Very easy to take apart to clean. Well made and don't cost the earth.
One of my two current favourite squonk attys, other being the Hadaly.
