hello, wondering if someone can should some light on my experience with the xhaler...overall been extremely happy with it...been using exclusively cartomizers on it...been vaping pretty good..put the noalox on it and cleaned it...but today I noticed that I was getting very little vapor..I went through 3 new cartos to see if some where duds..I refilled them too with fresh drips..atomizer was getting hot quickly..noticed only pressed button 1-2 seconds and had to stop (vapor too hot)...noticed very little flavor too...last all day..whether batteries were fully charged or not...then took it apart to clean a little tonight..put it back and wholah...press the button down 4-5 seconds now and gradually gets hot, much more flavor, and lot more vapor...runs great now..wondering what happen before? seems like it might of been running hot i guess for it to have little flavor and not much vapor etc..anyone know what cld have caused this? but I also noticed that now it doesn't fire all the time when I press the button..even though it vapes perfect now, now I have the button problem..wondering if it has something to do with the spring ?
