It's cast titanium! That's why you have some real weight to the VTR and why many say it's too heavy for them. It's built like a rock compared to the Smok Groove II I tried out with a cheap plastic body and poor grade chip in that one. Yet they can do a much better job with the Vamo lineup while Sigelei gets the favored rep likely due to that one always being priced higher! Sigelei 20w variable watt mod
I saw the V7 you got there Dude as well as the newer V8 which is a 35watter with the same options seen with the V6 however not seen with the V7 for adjuster the center contact pin and the smoke limit allowing you to raise that up from the typical 10 second cutoff to 30 seconds. That allows a much larger draw often needed with certain flavors more then others.
