Atomizers are the most delicate component of an electronic cigarette. On other models, mine have lasted one to two weeks on average. However, my experience with Joye 510 attys has been very positive: Those from my original kit received four months ago still work (although their performance has dropped off).
I
assume that these are
Joye 510 atomizers. Other manufacturers' 510s
may be good, but it is the Joye atty that has a track record.
Are you keeping the atty moist? Even it you use carts, you should regularly drip a couple drops onto the wick (i.e., into the the center of the tube; I don't look where it goes). [Because of that, I stopped using carts a long time ago.]
Are you using a high voltage
mod? As wonderful as those are, they are very demanding on the atomizer. Keeping it moist constantly is critical.
I don't recommend boiling them or using coke. [I've lost more attys that way than revived them.] Simply blowing them out, perhaps more often than every
three days, should keep them going for quite some time.
Failing all that, you may want to change suppliers. Your current supplier may be stuck with a bad batch.
I know that I have not provided a guaranteed solution, but I hope those suggestions help.
