I recommended Modern vapor to my niece and she has actually doesn't smoke anymore ...so to make a very long story short she has had nothing but problems with her LUX batteries and I just feel so bad because she made all of these purchases under my recommendations and now her batteries are not keeping a charge even with a brand new bat and a new charger.I told her to send an email and she did with no reply! And then she even tried calling and still no reply .so I'm hoping that someone will get back to her soon..I personally had only one battery issue and it was resolved quickly so that is why I always recommend MV to everyone who wants to start vaping!
