So far so good!
Good coils to use. Just make sure they fit your piece.
The description states .4 ohms. I received .6 ohms. They work fine, just not what I was expecting.
These coils were always stocked as the .4 ohm, which were my favorite, longest lasting coils. Great for a chain vapor like me. My last purchase arrived in the .6 ohm. I didn't think to check this because they never carried .6 before. The .6 are reminiscent of the M2 coils, low wattage, burn out fast, and terrible on my mod. Better suited for the SMOK pen imo. Dissappointing
I like these as well as T6 and T8.
