FYI - the volt is a KR808D-1
even though i normally would not recommend an auto battery I have found these to work much better than most.
Yes the
juice selection is very limited at this time but since I buy my
juice from various vendors and fill them I do not find that an issue.
The battery life is decent for this type of model and I must say the vapor produced by these cartomizers surpasses any others I have tried.
I personally have various Mods, ego and many other types of PV's and truthfully this is the one I prefer due to the ease of use, vapor production and minimal hassle. I have been
vaping for a long time and have tried many of the vendors all of the ones suggested are very good. I wish you and your mother the best in this journey.
