I have mine set to 7.0wats at the moment it doesn't seem to be guzzleing juice as much. Still getting a good throat hit not nearly as much vapor though. wish I could use one of my shorter tanks like the ib carto for some reason it or any of my other tanks work the only one that works is the iclear30. Not sure what I am doing wrong. As for the person asking about wraps I'd get one just because I am a bit ocd when it comes to scratches and fingerprints. They are beautiful mods though so I am going to look for a clear wrap.
