So I'm curious if this might help with the atty problems I've been having.I have a DSE901 and love it but the atty's don't last too long for me.If I have a good atty it will just burn out and die in a week or two if I have a atty that isn't producing alot of vapor it will freaking last forever.I have about 5 atty's that produce hardly any vapor but they never die.I've tried many methods of cleaning them and dosen't help the vapor production at all.So I was wondering if I'm correct this cartomizer or what ever you call it will fit a 901 as well and I was just wondering if that is true?Also wondering can it be re filled by me with my liquid also do these seem to last a long time or die quickly? Thanks for any input.
