Most of these so called pen vaporizers aren't truly vaporizers. They are just electronic pipes that combust whatever you put in them & should be reclassified lest you get sued for false advertising.
This 3 in 1 has nice concentrate Chambers but still uses a heating coil with no control over the temp. Therefore Not a real Vaporizers. I bought it thinking it was different but same old scam. Seriously they need to say up front that these combust whatever you put in and DO NOT vaporizer anything.
