You are building it wrong bro. You need to first off use vertical coils not horizontal , it makes a huge difference and i found nichrome sucks bad with these especially thicker guages. My problem with this RDTA is it leaks BADDDD when tilted on its side overnight so i just leave it upright.
I have over 50 drippers and RDTA tanks and always buy the newest ones that get good reviews and honestly i find my favorites are eleaf lemo drop or lemo 2 "can find for $15" for mouth too lung using 26 guage and for lung hits i like the griffin 25 top airflow by far and its simple too build on and for flavor nothing even comes close too the bellus in single coil mode but you have to build and wick it right.
26 guage kanthal is perfect or 26/32 clapton is nice too but it gunks up super fast.
