I think the original? Got it from halo, basically rebranded starre tank. Was trying to support the folks that helped me quit, and they were having a sale.
Ugh so its not just me. I haven't liked tc so far

and bought 2 packs of kanthal coils. Damnit
I think it depends on how you use it really. With the stock drip tip its a bit different than the slammed 510 tip I use. I kinda go back and forth between dl and mtl depending on my nic craving, the juice I'm using, and the airflow etc. There is a good airflow in it and can change it from barely any to a ton, based on preference. But I've found it really shines at 50-60w with the .6 coils personally. It can go higher or lower if you like more heat, but for 99% of my juices (mostly desserts) its perfect somewhere in there.
The best part is I can't get it to dry hit at all until 80+ watts. I got this after hating everything about the subtank because it was constantly dry or burnt (I'm a chain vaper) and it was a night and day difference. And so far haven't had any leaks, I drop it in my purse several times a day and leave it on its side and everything lol
