zipper

Hi I'm sorta new to cloud chasing and I recently built a zipper 0.10 ohm coil build on a velocity rda clone with a kanger kbox 200. I've been using it for a few day and my entire set up seems to be getting very warm. Is this to be expected with very low sub on coils or should I be worried ?

It's a total of 6 pieces of 26g a1 kanthal and it ohms out at .10 for dual coil. I personally don't feel that it looked very good like others on YouTube looked but let me know what y'all thought.
