Got 2 of this from Fasttech. Waited 2 weeks to ship and 1 month to arrive. Had high expectations first but dissappointed when tried it. Tried it out of the box with stock coil. The flavor was a delicious rubber, silicon and plastic taste

.
Cleaning process:
- Dish soap bath for an hour.
Test again: rubber, silicon, plastic taste.
- Alcohol bath for an hour
Test again: rubber, silicon, plastic taste.
- Toothpaste + toothpaste + water bath
Test again: rubber, silicon, plastic taste
- Alcohol bath for 2 hours (both o-rings), boiling in hot water for 10 minutes without the o-rings
Test again: Success !!!
I spent most of the day to clean this tank. BUt then, it was done. No leaking problems, even JFC open to maximum with 50/50 pg/vg. It's pretty easy to wick it.
Tried 26G kanthal, 3mm, 10 wraps @ 1.5ohm (spaced) and other tank 24G, 3mm, 13 wraps @ 1.3ohm (contact). Both of them were close to the air hole. Not high, but as low as possible.
The first one with AFC close to minimum (almost close) it's cold and smooth, great for MTL vapers, similar to KF4 and Taifun GT-T but more vapor as bonus. I tried it at 10 watts.
The second one was little hardcore for me since I usually don't go more than 12 watts. I had to go to 18 watts to "start" it. It heat slowly and cold slowly. But flavor and vapor production was there (great). I think Ill like it with lower nicotine juice. It was warm to hot. I think this config might be good in cold days outside since low power setup has no taste and flavor in colds days outside.
Usually the flavor production is better with 2.5mm coils compared to 3mm with other tanks I have. 2.5mm will be next to try in this but it migh cause wicking issues.
I think Ill like this tank. What I don't like is the AFC is to loose, it might be tighter. JFC is not aligned with the deck wick hole. Not big deal since juice can reach the cotton from the channel. And of course the cleaning process that was...
Last thing, I changed the drip tip to something tighter, similar to Aspire Nautilus because I'm more MTL.
This is day 1. Will keep posting about this...
