Is there a benefit to leaving the O-ring out? I've been putting off refilling but I'm getting ready to try it.
By the way, did my first sales pitch today! I felt so guilty, like some kind of used car salesman.
I was in a parking lot and there was this senior gentleman standing outside his car smoking. I walked up to him and asked him if he'd ever seen an e-cigarette and pulled mine out. We talked for a long time and he asked me to wait until his wife came out. She doesn't smoke and has been bugging him to stop. He smokes Cools and I happened to be smoking a Cool carto at the time so I showed him how everything worked. They were both very excited about it. I left all my cards at home - damn - but I wrote down V4Life and how to Google them. I do believe I made a convert. I can't tell you how many times I swore to them I didn't work for the company. 
P.S. His wife was very grateful for the info. He just had pneumonia and they both really want the smoking to end. I was glad to help!
