Sorta off topic, but I've been using a no-name $10
Velocity RDA clone for a couple weeks now, and man, what a great design for Ni200 builds. Tons and tons of room to run those redonkulous long coils thicker Ni200 need to reach min resistance when using duals.
30ga, 28ga, even 26ga can be made to work at the 0.1 ohm range of the DNA40 and Rayn clones and more importantly, room to make even
longer coils if you (like me) don't trust a DNA40/ChiNA40 down below 0.15 due to refinement issues.
Dead simple to build on, can't stress this enough, it's just great in that regard. Tons of airflow options, from a good MTL to airy as hell, and easy to adjust. You want clouds, it does clouds. You want flavor, it does flavor. You want clouds and flavor, it does clouds and flavor. Nice chuff cap (I usually don't like chuff-style caps, this one is an exception) and a 510 drip tip adapter if you want to roll your own. Huge juice well and leak/over-dripping resistant. Can close airflow all the way down to be pocket friendly. Anodized black version looks great on my black flasks.
Barrel design with a locking tab means you can crank it down tight on your mod for a solid connection and not worry about adjusting airflow loosening the 510 connection.
One downside, it really needs more than 40w to really shine if you're using long thick dual 26ga or twisted dual 28ga coils, however, 40w is enough for dual 28 non-twisted, or dual 30ga, at up to about 0.15 ohms. 26ga works better on my SX M Class thanks to the extra power. Speaking of 30ga, the grub screws can capture it, but they need a little extra care with single strand, twisted not so much.
Another downside, my unit has a long-ish 510 post, so there's a quite visible gap when using it on my Waidea flask, about thick enough to pass a piece of 26ga wire under it. But since it's black, it doesn't jump out at me when using it. Sits better on my Kangxin with Varitube spring loaded 510.
Also works a treat (obviously) with standard wire.
This thing is so good, I'm going to order an authentic just to show my love. For me, it's a game-changer with dual Ni200 and dripping. Hope to see a tank system using the same sort of build deck soon. Also has bottom feeder version that might finally make me move over to Squonkville.
