Hey guys! Sorry if this is not the right place to ask this question. My son bought me the Smok AL85 on August 8th. I was a 1 1/2 - 2 packs a day smoker and decided it was time to quit! That being said, I am a chain vaper for sure! I have taken 4,249 puffs since then, and have had to replace my coils quite frequently. I used the coils that came with the kit. 0.4. I vape at 55W(if that is what that means lol). I am only getting about 1,000 puffs before replacement. Is that common? Is there a coil that would last longer? Any advice would be greatly appreciated! TIA!
