I have the SLB VV on a Vivi Nova 3.5 tank and LOVE IT! I just ordered the sleeve that will cover the eGo threads and set off the complete look. My only complaint matches everyone else; the firing button. While I like the fact that a flush button means I don't have to turn the device on and off every time I put it in and out of my pocket I would have loved for them to put a small nipple on it so it was more tactile to find.
Been thinking of making my own "nipple" for it, maybe some kind of glue that I could place on top of it that would raise it up just a touch. Anyone have any ideas on what I could use that wouldn't destroy or weaken the rubber that is on it? Was thinking hot glue would work if it didn't melt the rubber underneath but not sure how strong the hold or how well it would stay would be. I just want something that allows my finger to find it as it slides across the rubber ring so I know I'm in the correct spot to fire it. As I said I like the fact that it is recessed as opposed to sticking out like a standard eGo firing button.
This might work. You can get cabinet bumpers from Home Depot or Lowe's. Hemispherical Bumper Feet | Bumper Specialties, Inc
