You know, and this may sound like simplistic advice, but I don't go shoving whatever self built whatever on my mod and then complain "what is it good for."
It's good for learning "different people like different things," or perhaps, "I need to learn to make my own coils, because at least I am TRYING to know what I'm doing," or even, good for learning, "That was a nice friendly gesture from my acquaintance, they can take up a little room in the trash for a while until it goes out to the curb, and if he asks, I can tell him they were great, but very long lasting or, if wanting to be more honest, I can say, they ohms were too low for me, would you like them back?"
I mean.... Many things are not "good" for vaping. Jam and jelly are just terrible for the vaping experience. I don't try to vaporize water, because it's not good for my equipment.
Sounds to me like you are hanging with a low resistance crowd. You don't have to mimic them exactly, so I guess most of all, they were GOOD for learning what does and doesn't work, coil wise, for you AND your equipment.. Etc."
