I got one but it's the older model 2.0 or shit like that. It works but the bags ain't big enough, it leaks, and it's pain in the ass. I can get only 3-4 hits off the bag then it's gone. Don't worry about the plastic melting. It's probably a PPS or PEEK material that has a high HDT (heat deflection temp). I know plastics better than pot. Overall I'd give my model a D+. Save your cash and get a volcano. If you could buy it for 70-80 bucks the Vape air wouldn't be that bad of a deal. But not 149!
Oh yeah, it makes a lot of noise too.
