Joyetech eGo AIO ECO Coil 0.5ohm (5pcs/pack)

I have only recently started using the device that requires these coils, first thing I made note of was that they are a cotton coil not a fiber coil, and they last a long time between changes, by that I mean a week or more even with heavy (stress) use. Nice to see they got it right the first time. I do recommend this product very highly.

Get them while they last. You won't find a cheaper price. If you have read these are poorly constructed coils, it is only because those users did not understand they had allowed juice into the battery connection and it flooded the coil. It is very easy to blow out the coil when this happens. This is actually a very good product. But think of the model like a printer ink cartridge. Plan ahead.
