The first question that gets asked a lot is "Can I vape with the Arizer Solo while it is charging?" The answer is yes, and no. You are able to vaporizer with the Arizer Solo while it is charging but you will need to purchase a separate Arizer Solo power adapter that is not included in the standard package. You can find the charger here: https://www.vapornation.com/arizer-solo-power-adapter.html
The second question that often arises is simple and straight forward, "Can I purchase the bent glass stem individually?". The answer is yes! Many people prefer the bent Arizer Solo glass aroma tube for its convenience and ease of use. You can find the angled stem here: https://www.vapornation.com/arizer-solo-glass-aroma-tube.html
The third and final question I will expand upon is "Can I replace the battery after it stops holding a charge?". Unfortunately you cannot replace the Arizer Solo battery. However the Arizer Solo battery does come with a 1 year warranty it should also be noted that we very rarely see these batteries malfunction.
