The Natural by Vapvana

Is anyone using this with any type of dry glass cooling unit like a j hook? DDave's dry cooling stem or any other setups?

I've been testing 630 using rdk300b with the proper PID settings for a 20mm coil and I get a perfect burn, anything above creates a burnt halo.

I am actually enjoying this device. It's for the purist but it does have its drawbacks. I will be using the screwball when I don't have time to wait for it to heat.
