I just ordered one of the ruyan vegas disposable e-cigars. Hoping this will be the answer to my e-prayers as you don't need to inhale the vapor to get a nic hit and I know that PG is safe to put in your mouth, it's the lungs I'm worries about. Also, since it's disposable, don't have to worry about charging it or cart refills. Now the question is how long will it last cause at $45.00 plus shipping they're pretty darn expensive, but if they live up to thier claims they may just be worth it. Has anyone else bought one of these? if so any info would be great.
