Just purchased a new protank 3 from a local shop in Corpus Christi. Watched a few YouTube videos on how to fill and maintain it. I noticed that in one of the videos the guy compared the protank 2 to the protank 3. The difference was the atomizer heads. My concern is that the atomizer heads that came in the package are not the ones in the pictures and videos. They look like the ones for the protank 2. The package looked authentic and even had a card to check it's authenticity on the kanger website( I've misplaced the card and trying to find it now.) is it possible to purchase a fake in a brick and mortar store? Everything looks legit on the tank even says protank 3 on it. Did kanger possibly change the heads? In advanced for any info
