Currently my TOP bottom fed atomizer and I have used many.
I have already acquired 3 of these little beauties and have done the following builds:
On the first one I started off with a single coil in between the post holes, right above the drain hole. This, however, made positioning the air holes problematic, but still gave impressive results. Made with 26 g Kanthal, 7 wraps, 2,5 mm ID at 0.87 ohms. Wicked with Cotton Bacon V2.
Next up was 26 g Kanthal, 8 wraps, 2.5 mm ID at 0.95 ohms. Initially wicked with Cotton Bacon V2, but later, after tilting the coil, with 2.7 mm ceramic wicking. Currently in use.
My second OL16 is graced with 27 g SS304, 7 wraps on a 3.5 mm ID at 0.77 ohms. Wicked with 4.0 mm ceramic wicking.
The third OL16 sports dual coils, 28 g Kanthal, 5 wraps each on a 2.5 mm ID mandrel at 0.58 ohms. Ceramic 2.7 mm wick.
- First, and foremost, it is excellent in all three elements - flavour, vapour and throat hit. Like someone on ECF said "Reduced chamber resulting in very, very good flavour. Effectively, it's 14 mm performance for flavour with larger atty vapor - quite a nice combo.".
- Flawless craftsmanship.
- AFC gives many options. Single or dual. Wide open for direct to lung hits (some say mid DL) and closes down for pure mouth to lung.
- The built in heat sinks works great - I use SS or titanium drip tips and no heat gets transferred from the atty. Being so small the atty does get hot. Compared to a Nuppin and RM2:
- Despite side air holes I have experienced minimal leaking and carry it in my shirt pocket with confidence.
- The way the posts are situated opens up the interior for very large ID coils. I have done a 3.5 mm ID coil, which fits with ease. Am sure one can go even larger if need be.
- Each post has two holes for wire. I have found that inserting the coil tails diagonally works best and makes for the most secure fastening and connection.
- Unique grub screws to prevent cutting wire:
