I wasn't sure where to post this.... I own a SS Apollo short vtube, and it's advertised as having a built-in eGo adapter, which it looks like to me, but I've tried to attach eGo clearos to it and they won't screw in. I've tried the stardust and some other brand eGo clearos; no luck. Is it just me? I Do have the separate adapter, and they all fit fine with that attached, but it's a no go without it.
