Just wondering how much difference between these 2? The Obviously the "Cloupor Hana dna 30" is a box & sigelei is tube. I've read & heard lots of revisions have been made to the Hana thus time around. The Connection is different w/ sigelei & device is bigger. I read the center pin is spring vs other has to be adjusted. Any advice & comments from all of you that have 1, both or know someone would be great
