$99.99 There's a knock-off version of it on pipesdaddy, it's gained the title of "The Infamous $40 Bubbler." If you're on the look-out for some glass to pair up with your LB, I recommend smaller-sized pieces. Large bongs can be milked, but you need some patience with it. Smaller tubes milk up nice and quick and can be cleared fast enough for the vapor to not become stale.
This thread is fairly large at 90-something pages, but if you look back through the last 10 pages or so you can get a feel for what we're finding for budget buys that don't compromise too much. There's some goodies to be found for $40-80 that I could totally see pairing up nicely with a Launch Box
There's a video around here of a LB milking a Mobius with an oil hit, so don't think you're limited to small pieces!

Yeah, that could be it. The LB gets warm with use, which doesn't help much either. I guess if stealth were an
absolute priority, you could toast/decarb the bud beforehand and evaporate the terpenes, but then you lose the taste, which is part of the experience (plus the terpenes have medical benefits and contribute to the high!). Your weed is just dank, there's really no other way to put it
I don't want to say "vape lesser-quality weed" either. And the fact that the LB is a conduction vape also doesn't help with the smell factor.
