Been using a TA3 with a wooden Tempest stem configured with open airflow. I love the simplicity of the head, fewer parts than a Tempest, and the design feels more industrial.
The cooling stand is effective, I did think it would have more weight, I'm considering gluing one to the bottom. I use a leather strap to unscrew the two halves of the head.
I'm still trying to figure out the best configuration for the wand. Like other commentors, I have found using the same settings as the Tempest disappointing. My current configuration is similar to that for my Dani Fusion 2.0, 400C, but wilth the Tempest insert, and I try to get the majority of the heat focused on the battery.
I made the mistake of trying the dynavap insert, it swabbed black inside the cup after using, I'm retiring that to the trash. Glass cups all the way.
