I had been having lots of issues with my istick 20w connector the past few weeks. I would get atomizer short all the time when my tanks were screwed down. I searched around here and found that many people were having similar issues and it seemed to stem from the O-ring being a piece of junk. Well I read on a UK forum of a guy that used the rubber band from one of the many mini screwdrivers that come with atomizers and removed the O-ring from the istick and placed that in there. I just did that and it works flawlessly. So if any of you are having that same issue, and have a spare mini screwdriver around, it might just be the free fix you're looking for.


1) power your device off.
2) remove junk o-ring from device connection, using a pin or something small enough to pull it out.
3) acquire mini screwdriver black rubber band (o-ring)
4) place it over your 510 center pin, may take a little fiddling to get it wrapped around.
5) push the new o-ring downward so that it somewhat tucks beneath the 510 connection, only a little bit of the o-ring will be left showing.
6) power device on and place an atomizer, adjust if necessary.
I take no credit for this method, I just thought I would share it.
