I recently ordered a purple ego twist from constantvapor.com as an early christmas present for my girlfriend. After only a week of using it the button stopped working. I contacted constant vapor and told RJ the situation and he sent out a new one before we could even send the other one back! As in, the new one was in my mailbox by the time the old one was dropped off at the post. Amazing customer service, This guy sincerely cares about his customers. Will definitely order again!
