After using the Ares for about 2 weeks now, I can throw in my .02c.
I never smoked (well, in college I did but that was a while ago), I was a dipper for 18 years. DTL vaping never appealed to me, and I always liked a tight(er) draw. I used the Nautilus on the 2nd air hole, and the v2 with 2 holes open, because that's what I like, and what reminded ME of MTL.
First, the Ares was super easy to build and wick. Again, I have never rebuilt or wicked anything, and was always too scared to try. I watched Phil's tutorials, and they are literally the reason I bought the Ares. At first, I used too much cotton and choked my coil a bit, but I tinkered, rewicking 2 Ares almost every day to get it right. I even MADE my OWN coils! The included wires, cotton, and build tools, along with the videos allowed me to do this. I even got a pair of ceramic tweezers and made a contact .8 ohm with the included wire, and I love it.
Leaking. My silver one has leaked through the air holes, but I believe that was a result of way too much cotton outside the coils, causing juice to go around the barriers. Less wicking than I though I needed, problem solved for me, no more leaking. Also, a good wipe down of everything (orings, glass, sport where orings sit), ensured a nice, tight fit, with zero leaking.
Draw. For me, its the way I like it with 2 air holes open. Draw, like flavor is subjective. I don't base my draw off of years of smoking, but rather what I remember from it, and I like it. Any tighter (FOR ME), and I don't take hits the way I like them. To each their own.
Flavor. Welcome to flavor town! I diy my juice, and my usual gold ducat tastes amazing (although now I see how it treats coils, its super dark), and ry4d +AP is great too. Also layered some nicotine river Kilanca with mint and koolada (total 4% flavorings in 50/50), and its amazing. I can say it crushed the Nautilus v1, and is better than the Nv2.
Also, the tank looks really nice, and is well put together. Being a beginner, I have only 2 mods (both 22mm). An innokin coolfire pebble and the Zelos mod the N2 came with. The Ares looks pretty great on both of those, although I do not have OCD about the TINY overhang. I was actually anticipating it looking MUCH worse than it does, so I am happy.
I know I have been long winded, and these are impressions from a total beginner that can't compare the Ares to other RTAs. I really don't see myself needing to buy another tank for the forseeable future. Have one Ares for fruits, etc, and one for Tobaccos, seems I am all set for a while.
This trip has made me was to try more coils, wires, wicks, etc etc, and appreciate all the info on this site. Anyway, that's more like my .04c! Thanks!
