Hi,
I have a little advice for a newbie... do a LOT or vaping to start with get comfortable with the Juices and the nicotine level that satisfies the analog habit.
Go to a local brick and mortar vape store and look at the hardware (get to know the vendor) and find his knowledge base (whether he is just a seller or whether
he is sincere Vaper).
You are eventually going to upgrade your equipment but not all equipment are equal some look cool but if you are holding the device for long periods (as I do) they become uncomfortable.
Good luck and enjoy the new found hobby...and enjoy a longer life...
Jim
