I've had nothing but issues with my Zeus Dual. It normally just sits. You can try to place around a 0.4 ohm coil or setup in it, making sure you wick it properly as the atty is finicky. I don't get the best flavor from mine and chain vaping is not its strong point even with lower builds. I understand it's not affordable to just buy another atty after just buying this one but my Pyro 2 is certainly the difference between night and day even if it's a Rdta and the tank is only 4ml. Hope this helps and I'll try to build on mine this weekend to see what can work with low and higher builds. Try to thin your cotton just a tad if it's burning a tad to start with. I have my build on a .48 right now and it keeps up decently but isn't the best atty I have.
