IMO this is a really good designed innovative Dripper (i ordered one)
Advantages from my sight:
1. Re-dripping is perfect. Take out the Top Cap (with Drip Tip) and pour some liquid with a watering can
2. The oval size and the notch is great. Auto-aligning-to-the-coils-design!
2. Good AirFlow Handling through Top Cap (see size of notch) & rotatable Drip Tip.
I know no other RDA/RBA that can manage "both" sides of Air Path...
3. Spitting Coils bother no more - they can spit as long as they want
- see Air Path in Top Cap / Drip Tip
You don't need a 70 mm Drip Tip...
4. Long Airpath -> much Steel to heat -> Cooler vape on dual coils (weight: 74gr. stainless)
The incoming air comes through one or two (notch setting) holes through the groove in the top cap down the
main body. Because of Auto-align air comes to the coils and up to the inner top cap - after one 90 degree it comes to the
second Air Control (Drip Tip), after another 90 degree turn up in the mouth
I'm really exited to try that baby!
