I tried the Molecule last night and am pretty impressed.
With relatively little power, it vaporized a popcorn kernel sized bit of crumble in seconds. The inhale was so smooth I thought it was a weak, terp-only hit. But I exhaled an enormous, good tasting cloud. I was really impressed with the taste and effect from a 4 second hit.
I've never liked the metal coils on the Sai. Getting temp control to work properly was always a pain in the ass. And every hit produced a copious amount of reclaim. I used this thing pretty extensively last night. It produced very little reclaim if any at all. And it's possible to Q-tip it.
The Temp Control was very easy to get going as well. This is the advantage of having a respected e-cig coil maker producing the vape. The TC works flawlessly. The flat SS316 coils eat up mostly everything in the quartz bowl, with great taste. I know many people are sensitive to metal coils. But I got no "metal" taste at all. In fact, the only non cannabis taste I could detect was that hot quartz banger mouth feel when it started running a little dry.
While it's very well machined, there are some "fiddly" pieces. I've seen reports of the quartz bowl breaking. And it seems that the only thing holding the quartz bowl in place is the coil leads, so you have to be a little delicate when servicing and loading the bowl. I also don't love unscrewing the housing to load it safely. Would've much rather be able to pull it off with an o-ring setup like the Sai. But that's not a huge issue.
They included an extra quartz bowl, o-rings, and 4 extra coils. I think this thing is a tremendous value.
I'll probably pick up another unit to use with the quartz crucible and give that a try. I'll probably like the taste from the crucible more. But I don't know for sure. The instant vapor and true temp control that vaporizing directly on the stainless steel produces will be hard to beat.
Overall. I'm impressed. The Molecule uses safe materials in an affordable device that works really well and will last basically forever.
