“The quad coil is the perfect coil setup. The concentrate sits in the center of four coils surrounding it so the concentrate doesn't goop up the coils the way it does when you put it directly on the coils (as with a single, double or triple coil setups.) The battery life is great, but the power button needs a redesign. The light is impossible to see except in the dark so it's hard to tell when the power is on. (They should take the power button design from the Regen. Easy to see when it's on.) So, in a nutshell, the Evolve Plus XL is a good pen. Good draw. Great hit. The black on black color is pretty cool, too. Order arrived very quickly.”
