After releasing the well-commented Fuji and Pharaoh 25, Digiflavor followed the victory and introduced the new Espresso 22/25, which they claim as the first genesis subohm tank, ensuring better flavor than traditional subohm tanks. Digiflavor Espresso integrates a well-balanced flagship platform with flavor-oriented GVC System, convenient top filling, and adjustable top airflow system. With the replacement GVC coils, you can have a wonderful vaping and easy building experience. Espresso also adopts a locking top mechanism with threaded functionality, which virtually eliminates leaking and flooding potential. The main differences between Espresso 22 and Espresso 25 are the capacity and outside diameter. No matter refined 22mm diameter version for compact use or enlarged 25mm version for expanded range, Digiflavor Espresso must be a good choice for premade coil fans.
