You're right Bklynzfinest, Boge does have a denser polyfil than Ikenvape or Smoketech. I've never had to wait to vape but I do understand not wanting to burn the filler, ugh. I've never tried a Protank 1,2, or 3 so I can't compare a cartotank to it. I've never heard anyone compare the two actually, you're the first. The only comparison ever made to a cartomizer are the rebuildables or drip atomizers. I just don't wanna put out the cash to try another clearomizer for the sake of trying it out to see if it vapes the same as a cartotank.
