I would like to thank gotvapes for all there hard work. I started vaping a year ago and failed due to cart problems. I have been smoke free for a week 12 days now due to these fluxomizers. I accidently ordered the HV for my hello 16(luv that baby) They are working awesome on it to my surprise. loads of flavor and vapor and great Th. Gonna order more of these puppies. Just dont know if I should stick with HV or drop down to 2.8 ish any sugestions would be gratly appreciated.
