I think an o-ring or two could work well for holding the stem, and if there was an official stem size it wouldn’t be a problem for most users. The ones who really want to use stems with different ODs (outer diameters) could still find different o-rings.
I would also like to be able to turn it off completely, but I do keep it in my pocket a lot and I don’t think it’s ever turned on in there. The button is small and basically level with the surface so it would have to be pressed and held pretty directly to fire in your pocket.
I could see it happening in a bag with a bunch of small stuff though, so if you’re packing it in a backpack with small things that could rest against the button I would definitely take the battery out first.
@oldbay The inception j-hook is nice! After an early review talked about imperfections and rattling pieces I was expecting okay-but-not-great quality, but while it is still a handmade piece with minor imperfections I’d say it’s quality and well worth checking out.
I don’t have other dimpled j-hooks to compare it too, but I do think it cools better than my standard Grav hooks and it’s smaller and more durable.
Also, I meant to respond to this a while ago:
This is not a problem with the inception j-hook, but I got an inception stem too and when I tried it in the FW7 the small connector stem with the silicon sleeve and o-ring was pressed right up against the inner tube so the draw was more restricted.
That wouldn’t explain the lack of vapor unless something in there was sealing yours off even more, but that is probably at least why it was such a hard draw. If you carefully position it you could get it working (although it may just slide back down), but I’m just not sure that it’s the best fit for a FW7.
