I like the Etna. It's very flavorful, has a super compact chamber (the airflow insert reduces the chamber size quite a bit) and very smooth airflow. The two- and three hole inserts will not let juice leak out quickly (or at all when left undisturbed) when you over drip or squonk.
Cons for me are also the small chamber size. That together with a very tight fit of the top cap make this dripper less suitable for dripping. You could drip through the drip tip. These are fairly narrow, so you'll often end up with juice on the lips that way.
The price point is reasonable for the quality of the construction and the finishing.
One important thing to note: these do not come with a beauty ring. Digiflavor reconsidered on this accessory and never communicated anything. It upset me because it will only look good on tiny mods this way.
