I tried 3 vapes (cheap crap mostly) before the Volcano and never looked back.

IIRC the Volcano is the only 'medical' class device - but I don't know about some of the newer vapes on the market. If price is an issue there are lots of 2nd hand Volcanos going cheap. Mine is 2 years old and is totally faultless.

If you could test drive some first though - that might help! I was lucky enough to try the Volcano in Amsterdam, but that's a whole other story...

Whatever you purchase you won't beleive how lush vaping is!
