Γεια σου......
If u ask me the best coils from the z coils lineup are the 1.6ohm and 0.8ohm for mouth to lung vaping
..
I was only using 0.8ohm with 70vg juices and had no problems and I have tired all coils and others wasn't so durable to me even..
Ok the 0.3ohm new mesh rdl could is good but only for rdl ofc
With 70vg juices in my opinion if it's winter and its kinda cold those coils may not work so good but with 50vg juice or 60vg works great always...
sometimes it can be user error also maybe he chain vape like madman no stop...or can be bad batch of coils cause I don't know.how many he tried and say they got burned...
So if u like very tight draw u use 1.6ohms and if u like a little more airy u use 0.8ohm...
I was priming.them with juice and then for first hour or something I was going slow without chainvaping them and I was good
