Hello to all here. I'm looking to get another mod and have some questions that I hope y'all can answer. Has any of you ordered from Vaprzon? I was going to order from Directvapor, but Vaprzon has the same device much cheaper. Just want to make sure Vaprzon legit and don't sell clones. The device I'm looking at is the Vaporesso Polar. On to the battery question, Vaprzon has the Sony 18650 VTC5 as the only option that I see on their website. When comparing the Polar starter kit against the Polar mod on Directvapor, they say that an external battery charger is recommended on the starter kit page, but do not say that on the mod page. What do y'all think? Should I get a battery charger also? For simplicity, I prefer to just use the usb port which it has. Directvapor also has more selection of batteries to choose from like the Samsung 20s 18650 2000mAh 30A High Drain battery among many others. Which 18650 battery would you recommend that would be the longest lasting between charges and what does High Drain mean? Many thanks for taking the time to answer these questions. I hope that I can get some feedback and place the order before it is not on sale anymore.
