Looking around the web I probably need to change my vote. All the white authentic Apollo's I find have a raw copper bottom cap, not white. And I see what the previous poster comment about the "o"'s being off. They do appear to be off. All the authentic photos I see the lettering is perfect from any angle.
Verdict ----- It's a clone, even though I can't seem to find a recessed button on a clone, there apparently is somewhere.
I have a clone Apollo, but the letters are perfect. It doesn't have a recessed fire button, but it is the hardest hitting single 18650 mod I own, and I own a few. There is no way anyone can convince me that the authentic hits $150 better than mine does, and probably not yours either. It will give you years of use. They're virtually indestructible. Enjoy it.
