I've searched every post in the maintenance thread and I am surprised that this question hasn't popped up-- How do you get a better/easier hit from the RN4081? The particular model I have is the Super E-Cigarette, two piece cartomizer style-- it's really REALLY hard to draw on. I've tinkered around with it a little bit and found that if the LED cap is removed and the (vacuum?) sensor is pried out a bit, it draws quite a bit easier for a while, until the sensor gets pulled back down into the silicone grommet it sits in. However, if the sensor is loosened up too much, it does not activate. I am considering using a small, fine metal file to make a couple more notches on the cartomizer end to increase air flow on that end.... Anyone else figure out a way to get past this issue?
