“Best pen I've used personally. I have the Evolve plus, with concentrate and herb coils, but bought this XL, and the quad coils gives off far better hits than it's predecessor. I am happy with my purchase, came 3 days after the day I ordered it.”
“This is an excellent pen for concentrates! I use mine for CBD distillate. You have to know what you're doing though. This isn't ment for big rips! You want giant hit get out your dab rig. This is perfect for on the go, smaller, more often, colder hits. Get it too hot it waists concentrate and the coil will leak inside itself. I'm no iron lung this device gives great hits and administers concentrate wonderfully!”
