Just to put things into perspective. Your whole house if full of formaldehyde. That stuff is really bad for you and it's in 90% of all furniture made and about 1/2 of all construction materials.

It is hard to make a vape purchase sight unseen but I've been really quite happy with my cheap chinese "Vapor-Tech" though longevity is truly a concern. I figure that if this blows up, I'll get a nicer one and thus have a spare whip. Though there's only like 6 parts electronically in this, you could probably replace the worn out pieces.
