To my knowledge, the LG and Samsung cells have not been duplicated/faked/counterfeited YET. As a matter of fact, the Samsung 25R was recently used to counterfeit a bunch of VTC5's so it would appear that cell is much cheaper in price right off the jump. What sells is the name, and since the VTC5 had such a wide following and was known far and wide as the "best" battery for subohm vaping it gained enough of an audience and had such limited availability that it became profitable to counterfeit it and dupe people. Sucks to think about it, but the more we tell people that the LG's and Samsungs are great batteries the more likely they are to be counterfeited...
