Here's the link to my setup from a previous post.
I need more time with this but I think @Zillacon is right on with both how nice it is and that it takes some fiddling. It addresses a longstanding need for folks who like to use dry glass to cool their vapor without flavor loss: it's usually dry, sometimes uncomfortably so. The Humi's a great...

And here they are put together. Please excuse that it needs a cleaning.
I just scoop enough flower to reach where the bowl starts to narrow, maybe 0.1g or so. Then add a nice "garnish" should you be so inclined (kief, hash, rosin, other concentrate) and just invert the naked Couchlog into the bowl - no stem required. The Couchlog head will make a nice seal with the 14mm injector bowl and then you just puff away.
Every heater is different but for this setup, I set the Couchlog to 4.5 on the dial. First hit is incredible. Pure glass airpath coupled with a very open draw and a lovely, powerful heat dump from the ceramic balls. I taste nothing but the flower itself. I love the flat glass mouthpiece and the hits aren't hot for me at all.
There's so much taste that often I salivate like crazy (a reaction I have to the terps sometimes) and I end up drooling like a cheap drunk leering at some cleavage. It's real attractive.
Second hit can usually finish the bowl but sometimes a stir might lead to a cleanup draw. There's very little drop-off in taste for me. All hits are either flavorful or spent with weak flavor, never harsh (at least at my settings).
If anything makes me cough, which is rare, it's the blast of terps hitting the back of my throat. I sometimes have to moderate my draw because if I get too greedy with certain terpy strains, then I might cough but never because of the heat.
