Almost bought an Arctic but saw the Matrix and Im glad I did...hadn't heard of it either, so I just went with my gut.
Nice tank, nothing fancy. Feels like a well made product. Airflow ring is real smooth but doesnt lock into place. The drip tip airflow is something I like that they added. Some people may not...I noticed that my airflow is different then the pics above. Ill post pics tomorrow or later on, (sorry). Anyways, my airflow is one long hole, 14mm I think I heard.
No machine oil on mine and it comes in a nice box. Has a glass tank, which is cool. There are no extras though, at least not with mine.
The .6 Ohm coils are good for flavor so far. Im vaping a max VG juice with it right now and because of the large rectangle cutouts on the shell of the coil, theres no dry hits. Blows good clouds...
Havent tried the .2 coil yet, will be a few days until I do..
Overall, its worth it if you want a Sub Ohm tank without having the rda (I have both), etc...it performs excellent in my opinion...again, there's nothing fancy about it, no extras BUT you do get what you pay for. Would definatly recommend.
