The kit is pretty well thought out, and works perfectly with a dimpled jhook. The vapor is definitely tamed enough for me through a dry stem, I haven't really felt the need to try it through water yet. I will likely DIY some kind of wooden jhook stand in the future, but the included glass stand did compensate since I could at least set down the hot parts. Also, the glass connector is clutch since it manages to stay cool enough to handle by the bulb at all times, for clearing the stem or moving the hot stuff from stem to stand. It'd be better to set up some kind of station rather than packing it into a portable kit due to the cooldown time of 2-3 minutes and the number of pieces. However it is perfectly portable to bring to the back patio, not likely your car, hiking, a concert though. The nature of using a torch and lack of privacy makes this less than stealthy although odor is less a problem.
It does extract fast; it has almost no absolute limitations to the amount of flame you can apply, but it becomes impractical if you push it much. While you can certainly use a kitchen torch or dab torch and get bowls hot in about 15 glorious seconds, I found that size to be overkill. I'm still able to heat the thinner heater (which is a nice addition for this reason, not just a spare) in about 40 seconds outdoors with a single flame Honest torch (of the sort that Lotus and Dynavap owners would use). Since this heater is so much more responsive than the larger Terpsicle and other devices, something in between pocket torch and dab torch seems ideal. You can likely use whatever torch you have, however, so the cost of grabbing this kit will be among the least expensive vapes available by a wide margin for many people.
My only major knock on this kit are that the included tongs are barely adequate to handle a round quartz heater, but the ones with the larger vapes are ideal. Those ones are spring loaded and secure and the heater is just the right size to fit them, while the included ones are basically tweezers. The spring loaded tongs can hold the heater securely when set down without burning your table or porch while it cools. Handling this vape becomes a lot easier with the better tongs, I highly recommend people grab them. The tweezers aren't entirely useless but I feel they may cause a risk of drops due to lack of grip, unrelated to the heat.
I found the bowl size to be perfect; you get a massive amount of vapor quickly and get a few thick, flavorful hits. I measured one bowl at .2 grams but I left a fair bit of room and didn't tamp it down. I found if I filled it near the top, the bowl would be a bit too restricted on a med-fine grind so I've gotten good results by just breaking herb into small chunks because the airflow is important to even heating and reacting to vapor production with your draw. The choice of heaters isn't that important, but packing the bowl somewhat loosely and not overfilling is fairly crucial to give yourself margin for error.
Since the bowl is so narrow already, just stacking up little chunks with gaps between them is probably better than ground herb for airflow. Stirring is fairly unnecessary, since the bowl is so narrow that it cooks evenly since it doesn't rely on convection fully. Removing the screen seems like it would also reduce restriction, but I prefer to keep it for now to reduce cleaning. While cleaning more than once a week or two seems unnecessary, there is a bit of reclaim in the connector piece after a few bowls, but the screen and walls of the bowl stayed remarkably clear just from blowing the spent herb out.
As for the flavor and overall vapor quality, you can get extremely flavorful and concentrated vapor. It's not a full convection piece, but you get a much more full bodied and deep extraction from your herb that provides plenty of medication from one bowl to last hours.
Overall it's terrific, especially for the price and it's easy to find good accessories to pair with it. But if you're planning on grabbing one of its larger cousins, be sure to cop the better tongs.
