I'm looking forward to trying more stuff out. Going back to the atomizer topic for a second then, have any of you worked out a reasonable expected life on a new atomizer head for something like a ViVi Nova, smok TiTan, or a replaceable Stardust? Since I realized I wasn't cleaning mine well, I've discovered that the three I've decided were "dead" in the last three months, have actually come back to life. The issue with me is that I am often running three or more tanks at once, so the actual duration of any one atomizer is skewed into oblivion. Would you say that planning for one to die every three weeks (assuming it is the primary unit you are using for that three week period) is reasonable?
