Oh dear...and here is very Ernest young Tom who apparently works at JUMOTECH- BEST E CIG MANUFACURE IN CHINA, very optimistic and I beg to differ. He certainly tries very hard help his customers with problems that were particularly common in devices a few years ago, which is a very good thing. Too bad really he doesn't advise folks to TURN OFF their mods when he advises his clientele to STICK a screw driver into the neck of their 510 connection! OUCH!
Bah, sorry I'm on my kids iPad as they highjacked my computer and I can't figure out the cut and paste. But it's on YouTube and called "how to solve jomotech lite40 problem - very easy. Very easy, yes Tom. Thank you.
Now indeed we owe China for this wonderful invention and to this day there are very, very good manufacturers and e cigarette innovators in china who turn out quality, reliable, user friendly devices for a very good price. Why don't you poke around the ecf library here, learn about your options and what you may like, ask any question you have, and we can likely get you into a great device, with a usages style and delivery that meets your needs and lifestyle, and a few yummy juices with good ingredients that satisfy you for depending on where you live likely under $50. Just think of all time and money you will save not buying cigarettes and how happy you will be if vaping is just as easy, if not easier then cigarettes. No ashtrays to clean, no need to brush your teeth and gargle every time you kiss your loved ones, no nasty smells in your car....vape smells goooood. My husband says my hair smells great all the time, and bless his heart he thinks I keep changing shampoos as our teen girls line the bath with various bottles of goo.
You came to the right place, and you made a great decision to start vaping!
