“!st coils I've ordered from ET, very quick to arrive which is good. Coils are awkward to rate as it depends on how high your vap is turned up and how often you puff on it. I have mine down on 5watts as I don't like to leave a smoke trail and as a truck driver I'm always puffing on mine. I've had my coil in for just under 2 weeks and it is still ok. The price is about what I normally pay.”
