The amber rose has airflow holes in the mouthpiece, which may be "carbed" or covered to lessen airflow into the atomizer. By covering this, you will have a greater vapor-to-airflow mixture and will see increased vapor during use.
This typically happens when the device is overtightened. Try unscrewing the cartridge or atomizer just a little bit and see if that improve airflow. If this does not improve the use of your device, contact firstname.lastname@example.org
There is a chance the battery has been damaged by overtightening of cartridge or atomizer, or possibly a faulty charger. Please contact email@example.com for warranty support.
