Hi I am new to this forum and new to using vapor pens and blu PRO® device, is it possible to clean Atomiser Heads and Clearomiser tank blu PRO because I was told by blu.com I would need to change these items about every 3 weeks, I also was looking at buying a blu ACE™ Kit and if the adjuster with it is more about how much vapor is released than how much strength of tobacco is released, many thanks.
