Thanks! I remembered seeing a pic somewhere here but couldn't find it again.
Edited to ask: How well does it work?
With a mini ego and the aspire, I'm blowing MAD CLOUDS. I'm very happy with them and will probably order a few more.
There is one drawback. I ordered 2 and discovered when they got here that the threads are slightly different where they stop and start. Like, when I screw an ego battery into it all the way, the button ends up at different places. ALSO, every one of my mini ego batteries have different threads so....I pair different batteries to different adapters and remember which ones line up or don't obscure the button.
There is enough tension on these or rather on an ego battery, to where you don't have to screw it down all the way. Using it as a stealth mod though, I prefer it locked down tight with no wiggle. YMMV.
