So I couldn't find a thread dedicated purely to concentrate vape pens and I thought it would be cool to see what everyone out there uses so let's see what you guys use! Please only post pens used for cannabis concentrates no ejuice ecigs! Gpen, atmos, cloud, yocan, vhit etc. Here is what I use! It's the EXgo W1 with nero technology by yocan. It's an amazing tank that produces very flavorful hits. It has no wicks or coils just the nero heating element
