Nobody wants the Dovpo? It's a great piece. Much better than a mechanical tube. Its dual 18650 which means long run time and very low voltage drop. It has a micro usb charger so it charges very easily. It also reads battery voltage and voltage drop as you hit it. I vape heavily all day and still have plenty of battery left at the end of the day. Then I plug it in at night and it's fresh in the morning. It has a magnetic door as well. And if you like mechanical tubes, the 4nine is as small as they get. Mine is black and has the v3 top cap. For sale!
