Love the device. It took a bit of getting use to coming from only using conduction type vapes in the past (pax, davinci). Once I figured out how to draw properly, it was night and day vs conduction. I’m using less product, the heat is on demand and clean up is a breeze. The chamber stays clean, no discoloration you would find with a conduction vape (pax, davinci). Convection is the way to go. The price, YOU CANNOT BEAT THE PRICE of this vape. It performs above its price for sure. A++
