How long do the coils last?

I've had a coil last 7 months - until I dropped it - and cracked the bowl. I used it regularly at around 18 to 20 watts, occasionally at 25 watts. Coil life will obviously vary depending on power level and frequency of use. The coil is embedded in a ceramic plate so will not deteriorate or effect the flavour in the same way as an e-liquid coil.

Check atomizer message, what can I do?

If you are getting a 'check atomizer' or similar message from your device, gently push the ceramic bowl into the metal base and try it again. The bowl is a push-fit (not glued which is good) into the base and is wedged with a metal mesh shimmy. This shimmy also wedges an electrical contact wire. If the bowl has been knocked or pushed it may have lost connection. The coils should last many months of average use.
