Had played a long time with the idea to create me an e-cigarette. Much looked on the internet and then I ended up with this model and provider. Delivery was prompt. Smoking is therefore very good. Evaporated very good and after a short very good at handling. After four days loaded for the first time. Class battery! Then had a problem with the charging unit. Had everything connected, taken in the morning and nothing worked. Wrote an email to the seller and very quickly get a call. Class service! My problem was solved but in the meantime, of its own accord. Still great! Had replaced the supercharger. Goods also super nice! Many Greetings, Rainer
