Remember these GonG bag adapters from 5-6 years ago
PlanetVape used to sell them
Magma put their logo on the piece, and sell it reasonably at $20
Interesting they offer this alternative now
Can search YouTube for an age restricted video by user "VolcanoTips" from 2018. He does an excellent job of showing this adapter vs the Obsidian method
It does work quite well
Takes the edge off of higher temp dense bags
Magma does not include the Keck clip. It is helpful. Prevents pulling out and dropping glass adapter when removing bag. Or, at end of bag, when pulling on bag to straighten it, it's very easy to pull out and drop if not for that Keck clip
Was afraid bag would tip the bong, but no problem
You head butt the bag at first, but after a couple draws the bag sags down out of your face. Sag does not impede subsequent draws, whether one-handing the bong or leaving it on counter during draw
Can understand some would prefer this over the Obsidian, maybe the familiar bong holding, gurgling, resistance... Or, want to save money
Many folks probably laugh and say "just hold the bag's mouthpiece against a 14 mm joint." But that's a two-handed pain-in-the-ass process compared to this one-handed leak free solution
Also ordered an Obsidian, gotta try. Ordered UV bacteria killing light box from Amazon for moist bags. Probably overly paranoid
