Using a eGo-T. Try it everyday, hoping it will work, but it hasn't happened yet. If I 'blow' on the mouthpiece the vapor comes out the connection between the atty and battery; but I can't puff and get a vapor. Any suggestions? PS: Of the two mouthpieces I've tried: neither fit or seat snug. Trying to hold it down and turn it around for each drag is a pain.
