Just got my first nautilus yesterday. Wow! I'm pretty new to vaping and have been buying a lot of stuff to try. At first I loved the PT3, still think its a pretty good clearo. But eventually it leaked and flooded. works well right after a rewick and recoil. This Nautilus so far is the best thing I've ever tried. I have a couple Aspire BDCs and tried to rebuild the coils. I guess it can be done, but I was not successful at even trying to get one coil working in there. I dont think I will even attempt it with the Nautilus coil. My MOD is out of service right now and have only tried it on a spinner. It will look much better on the MOD.
