A wonderful pod system, with a good kick. Uwell has implemented its Pro-FOCS technology in a sleek, well-designed package made for maximum flavor. Running at 11W and sporting a 520mAh battery this vape just keeps giving enjoyment! Don't forget about the awesome draw activation, to compliment the button fire. The Caliburn is a solid unit for a pod system with its aluminum alloy chassis. The pod itself is 2ml and easy to fill, feeding directly into the cotton for maximum flavor from this 1.4-ohm pod. Overall this is a well designed, well built pod system, perfect for enjoying nicotine salts or free base.
