The Aspire Nautilus X coils are a bit different than what we’re used to seeing. Aspire is calling the technology used for these coils “U-Tech”, which they claim provides superior flavor. Basically there’s two chambers with each containing a coil. The air comes in the top of the coil, travels down to the bottom (passing the first coil), makes a u-turn and travels up the second chamber past the second coil and out the top. It’s an interesting design for sure and it’s great to see Aspire trying new things.
