I'm trying to get back to using less herb. I don't know what actually qualifies as micro dosing but the TM does quite well with small loads. pushing the CU down far enough so as to only use the included domed screen is a fairly small load.
This is my experience as well. I have only used the TM exactly as it came - no bowl size adjustment, no stem replacement. My CU is pushed as far down as it can go while still allowing the domed screen to fit.
Before the TM my daily driver was the Grasshopper. The smallest TM load, with domed screen in place, is roughly 1/3 to 1/2 my typical Hopper load. I can extract it fully with 2 or 3 hits at temp 8. I do get a dark ring in the material, but the extraction still seems to be complete.
The TM vapor is much cooler than the Hopper vapor, allowing hits that produce more vapor than expected based on the "feel" of the vapor temperature.
The Hopper is still much stealthier than the TM, and it allows me to have about 3 sessions with a single load. Right now with the TM I am only getting one session on a single load, so I have to refill it more than the Hopper. Of course that is without experimenting with different bowl sizes on the TM.
I will join the chorus and say that vapor production from the TM is outstanding, as are the effects. It probably won't leave the house though - that's what my Hoppers are for.
Along with the provided VTC6 I also have two VTC5A batteries. I will start trying the VTC5A once the VTC6 has been depleted to a single vibration. It's a nice feeling to know you can buy replacement batteries for the TM easily.
