Not many reviews of this RDA, but as an owner I can say that I thoroughly enjoy it.
Personally I prefer the sleeve with the smaller holes.
Flavor is as good (or maybe almost as good as) the Goon.
The deck is better then the goon as it easier to build on and can hold bigger coils.
Build quality is just fine (though there were some complaints regarding the 22mm ver, which were apparently fixed).
So all in all a good choice.
