I receive an email from a china supplier introducing me to an ego battery with air-flow control. It comes with adjustable knob to control the draw strength. Attached is the original pic from the email.
Is anyone using this and how does it fair?
Currently, I'm doing air control on my own using the different types of adapter available.
