The Crown 4 by Uwell is hand polished. Patented Self-Cleaning Technology, (I know, I was confused too). The Crown 4 atomizer can absorb the juice in the condensation holder, through regular usage, and vaporizes it. It reduces juice leakage and waste to lessen the cleaning. The exclusive coil that they came out with for the Crown 4 is a double helix coil meshed. Makes it heat evenly and brings out the flavor in your juice. UN1 Mesh is a 0.25ohm coil better at 55-65w. Unsure if it fits the crown 3 coils yet. Coming to you in Black, Blue, and Silver.
