works
a bit less vapor than with the CU attached to a whip to a d020d
That's the one everyone also refers to as the Vapefiend adapter.
The negatives people talk about are
1. Screen too far from load. Solutions are a. add oil pad to fill space. b. use a 'pac-mac' cut top screen atop load (may scratch bowl?).
2. Poor fit, as described by
@Green Kiwi and others. Solution is to file or machine a better fit
3. No positive 'stop' when rotating into position. It is possible to crack Mighty's housing by over-tightening.
I also think this thing has some good things going for it, over, say, the Muzzmod. No adhesives used, for one thing. I've made two muzzmods, and love their function, but eventual separation of glass/epoxy in both has led me to stop using them (after scores of high temp sessions, to be sure).
I don't understand what you guys are talking about with clouds and the adapter or water and all. In my experience, taking the c/u out of the equation gives more vapor, cloudy or otherwise, all else equal, so I like both of these the GonGs for that.
As the video above shows, Mighty can produce voluminous vapor with c/u in place as well. I think we're talking about relatively small differences in these methods compared to say, temperature.
Since I've stopped using Muzzmod and don't have the other one, I've gone back to just what the critic is doing in that video, using an arizer right angle water adapter (these are 18mm male) onto my glass, which is made from a mason jar and a 5 inch glass downstem with shower head (from Oregonglassblowers). I custom made the lid to the mason jar to receive the downstem and a second arizer right angle glass adapter, for whip tube. I replaced that plastic arizer whip tubing with silicone. All my glass is 18mm gong. Just to add, most sessions lately have been at 205C.
I guess, and to round out this discussion, I can state that I think there's some loss of vape in my long vapor path, so I think the D-020, etc probably give a bigger hit; it's more direct. I am, however, quite happy with the hits I'm getting! I might go for more potent flower, but the hits are just fine.
