6v is a little too hot for me, but I just slapped a 5v battery into my Grand and it totally changed the vaping experience for me with it, wow!
Id like to know also....before I order. So you HAVE to buy theor charger too? Trustfire charger for 3.7V 18650s really wont work?
Sorry. Realized where we were after I sent. I adore my Reo. My apologies.
