Can Be Expensive
Just as others have stated, these do not last long, two maybe three days. Replacing them so often gets to be expensive.
I was told this was previously a double coil design and that the current incarnation is a single. Whether that has anything to do with longevity, I do not know, but these rarely last me more than two days. After two days, even with cleaning twice daily, it tastes funny, it's clogged, and it's so saturated with vape juice that it comes up into the mouthpiece. Considering dropping money on an entirely new system just so I don't have to keep buying 5 packs of these at stores, as they are never available online anymore. And the 5 packs actually sent the cost UP rather than down, the opposite of what you'd expect going from buying single coils to bulk. I feel cheated every time I buy a five pack. Aspire really needs to get their act together and design a better coil, or I, for one, will be using another system.
Best so far
No more leaks, great taste, but a little hot. 3 volts and 3 watts produce the best results. Anything hotter reduces the coils longevity.
Poor longevity and quality
Don't care for single coil replacement s
Miss the BDCs why don't you carry them anymore?
