Sweet! I didn't know if they typically last that long or he just doesn't vape much lol. I don't have much to compare them to but for the price based on reviews of other coils they seem like one of the best. I'll definitely look it up! I never knew you could do that on them.Oh yeah, 2 to 3 weeks.
And they are super easy to "re-wick"
Look on Youtube, many vids to show you how to do it.
