I am fairly new to this. I started out with the "basic start up" then quickly upgraded to the ITaste VV. I don't know if I got a bad one or, if it is something that I am or am not doing right. I have to charge it at least twice a day! Even then, it seems to die very quickly. Once it is yellow I only get about 8 puffs before it goes to red then about 4 more before it dies. My husband thinks that I created a "memory" on it and destroyed it. Any suggestions?
