I tried the RBA, but it’s not my thing 
, the flavor is different, and pre-firing, then releasing the fire button before finishing the draw so the coil cools down, so the cotton doesn’t burn, compressing the coil, or leaving an air gap 
. I also have a Vapefly RMC coil that I use for the Gunter tank, but I am a believer in the flat Mesh, changing it doesn’t take much time, it’s done in about 2-5 minutes 
, but well, to each their own
The term “expensive” is relative 
, the cotton with the strip costs about 150ft-200ft, which is acceptable since I change it daily because I don’t like the taste when the cotton and the strip get caramelized, after about 1000-2000 puffs, and besides, this way the fruity liquid always tastes fresh. I used to smoke 2 cigarettes, which at today’s prices would be 150,000ft
