“CP Couples” is a regulated dual RDTA device with unique design, its rectangular cylinder shape reduced the box MOD size greatly and dramatically improves hand-feeling. The dual RDTA atomiser design lets users vape 2 flavours simultaneously, and its appearance and performance are extraordinary recognition. The fire button is set on the positive of the box mod. Beneath it is a channel selection button, that is also the channel switch of 2 510 interfaces, which allows the user to flexibly choose to turn on the power of one atomiser alone or both at the same time. Users can enjoy vaping on their mixed juice flavour or single juice flavour.
