All of you, even the OP, should understand my second sentence: they're not built right. A big fat piece of cotton squeezes down to
almost solid to go through the coil. The misalignment of the coil and the wick holes show a complete lack of quality control as well. It's like they went to the assembly line for the silica wicks BCCs -- not the same people as the other lines -- and said "you're using cotton now" and never really designed or tested it.
I tried the SOCCs first with joy, I'll happily pay another 20 cents a coil for less work and better quality. One or 2 did give really good flavor at first but didn't last well at all. My most important flavor, the one that doesn't work in other kinds of tanks, was like "what happened?" though. Upon taking one apart, I found out why. I was almost surprised they work as well as they do.
I started out on an evod 2 when I first got into vaping...I like cotton wick coils a lot better, better and smoother flavor. don't let your tank get too low bc it can burn out the coil fast if the cotton gets too dry. Idk how long it'll last in that particular tank but I vape the aspire Atlantis and my cotton coils have been lasting me 3 weeks
This is not the dual coil we are talking about. I'm skeptical of those now too, but could be different... I've run my regular cotton rewick EVODs down to empty many times and it doesn't really cause a problem. I get off taste and low vapor, turn it over and look at it and yep, empty. A newbie might keep vaping beyond that point though.
