I have a KR808D-1 two piece kit and am having trouble finding full (16-18mg) menthol cartridges in stock. It appears that the juice is easily obtainable though. I understand that the cartomizers can be refilled and have even watched some you-tube videos on how to do it (courtesy of some ECF members-thanx).
My questions are;
1.) How long does the atomizer in these last? Or, how many refills can you do?
2.) Do blank cartomizers that are made to be refilled last longer than the so called disposable ones?
