I am brand new to Cartos and LOVING it, floating in a cloud of vapor 
Questions to the vets though:


Questions to the vets though:
- These fit a ton of juice - 2.5ml; how do I know I need to put more juice in? Are they going to burn if I vape them dry? (these are supposed to last many weeks)
- Since they hold so much juice, if I am tired of one flavor, how do I change to the next? Do I vape the whole thing and top it off with the new juice? Can I take the filling off, clean and put it back on?
if so.... - How do you clean them?
- If I fill a second carto with a different juice, can I keep carto #1 full, aside? Or do I need to empty/clean and store it?
- Do large cartos consume more batteries?
- When filling,how do I know they are full?
