I just started getting into ecigs. So I got a Protank 2. I was wondering if the Pyrex tank section is suppose to feel so light and plastic-ish. And was wondering if what I got was genuine. It did not have the holographic seal closing the box. It did have an authentication scratch off code to test on the site provided which was something I wasn't expecting so I am unsure if that is trustworthy. The base does have the logo and name etched on.
