I've been using Stardusts on my LeCig VV. It needs a 510-510 (or 510-eGo) adapter because it's a flat top. I had one Stardust seem like it was DOA, but switched adapters and it came to life.
I've been loving these things, but I always keep a loaded cart with me for if/when it hogs up from thick
juice. I've been rotating 2 of them every couple days for a couple weeks and both going strong. When they're working they work great, when they don't they need to be cleaned. Bunch of vids on this too, but I take the easy route and just shake out any leftover
juice (I save it for dripping) and then 1/2 fill with water put the cap on and shake (repeat till water stays clean). take cap back off and shake out excess water (kinda like shaking down an old style thermometer), blow out any water in the tube and then do a light dry burn. Let it sit (open capped) for the next 2 days till it's all dried (hence the 2 day rotation...)
