The structure and design is almost the same with CE5 clearomizer, but the coil is replaceable.
The wick is inside the metal tube, and there are 4 small home on the tube wich allowing just enough e-liquid to pass through.
It’s very easy to replace the coil. Just unscrew the bottom part of the CE5+ and then unscrew the metal tube which holds the coil. Replace that tube with another and you’re good to go.
