    This is the 5th & 6th HG2 I've ordered here and they all work great. Definitely live up to all the reviews I've read. Never been anything other than very satisfied with the quality, speed of shipping and customer service at Orbtronic.

    Genuine batterys

    Posted by Chad p. on May 8th 2017

    Buying genuine manufacturer battery these days is a hard task, as a vapor we experience fake knock offs being sold as if they where real and by looking at a battery it's very hard to tell sometimes if it's real or fake till you go to use it and it don't perform as expected so I decided to go to a reliable source for batterys and I also got them for a better price than I would have paid in a store for phoney batterys ! Thanks

    Great battery, but I think most people know that by now. Highly recommended as the gold standard for medium resistance applications.
