As usual, great review!
This is my new favorite RTA, until now it was the Reload RTA, the flavor on this is just as good (very close to RDA flavor), the airflow is better, and it’s way cheaper. I like reasonably restricted airflow but the Reload is a fraction too restricted for me.
I bought my first Manta around a month ago and now have 4 of them (I found them for $23 @ Fastech, so I bought 3 more).
If you don’t yet own one, buy one (or more), you will not be sorry!
