Ok, So having this for a couple of days now, I figured some things out. First, I don't understand why they would put the cap so close to the bridge. Melted mine the first day. I've cut it down to about half the size, cleaned it and went back to vaping. Then started watching videos and reading more of the forums. I believe the atty cover blocks the vent holes and contributes to the overheating. So I took it off and get a much better hit. Today I'm going to drill a couple of small holes in it, just above the threads, to see if that helps. I saw Doctor Vapor's video about using parts from the ergo end of a pen, put one on and think it looks cheap, didn't like it. I will say, after using the Duet that a friend gave me, I love the eGo. I'm extremely impressed with the battery life. I would like to know if there's an atty out there that will hold more than 3 drops of liquid. I'm disabled and don't have the money to experiment much. That's the reason for getting an ecig to begin with. I couldn't afford analogs, my friends, who all smoke, were helping me with that. Today I'm going to try out a carto. All in all, I am happy with the unit I bought though. One little tip for those that now have that smell in their house. Put cups of vinegar around the house. It will remove the analog smell. Hope you all have a great day.
