Im using the vaporesso NRG tank with .18ohm mesh. Mesh coils seem to last a week or two longer than wire coils. Another good tank that uses mesh coils is the horizontech falcon. This is an awesome tank and i get 3 to 4 weeks from the M2 coil and im a fan of sweet flavors like desserts and such. At the moment, im using a strawberry milk flavor. But the NRG tank with the .18 ohm mesh im vaping at 70watts with no problem. And expect to get at least 3 weeks out of it.
Thanks Cayote628, very useful reply! I'll test and see how long the mesh coils last me.
