@tylerj55 's tear downs did not only happen after torching. The components inside the nail are not ideal regardless of whether or not he torched it and I know from my friend who owns one that the nails begin to degrade and discolor quickly. Not saying it isn't safe because I genuinely don't know. But if you guys have had no troubles it probably is. I just think the bubblers suck for the price point and I would rather have a nice W9/Source pen setup with some DHgate glass.
He touched it before opening it with pliers, he said it all here before it was deleted. You can use a lot of material in things as long as they work under operating temp...Your friend is a bold face liar. If you take a look at these nails, one is used one is brand new... The center isn't darkened, scortched, discolored, or anything. However I do admit, I would like a ceramic nail, with a Ti core.
You like what you like, but you can't compare a pen even to portable enails even the weaker G9/Dr.Dabber boost, Dabadoo, etc. And I can't justify spending almost 200 bucks on something half the size, battery, glass, etc. 50 bucks more was worth it(IMO) as i have tried them.
