I have an authentic aeolus and an authentic tugboat. Both are constructed extremely well, with excellent fit and finish!
The aeolus definitely wins in flavor over the tugboat.
Where the tugboat shines through is that it is a little easier to built on,(not by much and an arguable point) the real win for it are the extra caps that flawless makes for the tugboat. Currently, they offer 4 different caps that I know of which lets me change the performance of the RDA by swapping the cap and that using the same build. They have a square cap(have not used that one)
A glass cap-which is great flavor
A slam cap-shortens the height, more airflow a little better flavor and bigger cloud
Anarchist cap - real cloud chucker.
- the caps do fit the clones
-both rdas will work on mechmods
