You were the one who brought up Kangertech. This thread is about the Triton, which is manufactured by Aspire.Are we talking Kangertech?
This has been hashed out a number of times. Anything that fasttech sells that they identify as authentic, is authentic. If it is a clone, they label it as "styled". And you can readily verify this from the verification codes on the packaging on the Kangertech website. I haven't purchased any Kanger tanks from fasttech, but I have purchased coils, and every single package of coils comes up using Kangertech's website verification system as authentic.
