“The Uni Pro OG is surely the step up from those silly battery pens. I need a second one as a backup or for trips, and I wouldn’t get another product because….um, why? So glad I got this one and stopped messing with the ooze twists. Don’t get me wrong, their regular 650 mah will do but this digital temp controlled, strong battery, sleek look and feel, the cart size adjustments offered…again, why? It’s definitely the smarter investment. It pairs nicely with 3Chi carts…temps from 2.7-3.2 hit smooth.”
