G PEN users!!

Thinking about getting a vape, time I smoke a little healthier. Anyways, any people who own or have used/owned I need your knowledge! Lol I am seriously considering ordering one but I have a few questions.
-do u get that plastic taste while medicating with the G Pen?
- can you use dehydrated concentrates?
- how does it hit compared to other smoking methods
- price??? I've heard from 70$-135$

Ps. Any info would be cool pros/cons. Also I've heard people wonder about the smoke the G pen produces while heating device when there is no concentrate even in the G tank. Anyone have this problem or know anything about it?

For your leaf herbs I would go with the Launch box which is about $120- or the Vapir no.2 but if you can afford it I would go with Pax by Ploom. That one runs about $240- though but well worth it IMO
