So I got the Veritas and gave it a good bath and set it up with a 28 ga twisted @ .8 ohms (single coil). I loaded it with a proven juice and to be honest I'm disappointed with the overall experience.
I find it way to airy even with the hole in back mostly closed. Once it's shut down there is no dripping from that hole, it becomes a top dripped. Now maybe it was my build but the vape have the flavor or production I antisaped. It didn't even come close to the new Viking I just picked up. I did pick up those thumb screws in the link. While they are a little pricey that make building real easy.
As with many RDAs, I find that a slight tweak here or there, or even a slight misstep can make or break this atty. Not saying it will be for you, but for someone that has had this atty since it came out and done numerous builds on it, it never ceases to amaze me how one little thing, often unknown, can take this atty from a dim vape to glowing. I will also say that the airhole works best while open all the way -- I don't even consider it to be a adjustable airflow. Good luck.
I imagine you did the Faceless build on it? Can you take a pic of your build?
