Got my Hana One in today. It is indeed light and compact and it does indeed fire if you put any pressure what so ever on the face plate in the area bellow the fire button. This is a great big fail to me. I can never trust putting this thing in my pocket without the stupid 5 clicks to put it in and 5 clicks every time I take it out. Other than that, I like it.
Interesting Capt....I tried your "tip" of pressing on the face plate below the fire button...but my ONE appears to only fire when I press the Fire Button...
(I can...in certain situations...see an advantage in having one with your "larger Fire Button".)
As for Out & About...although the Hana ONE is noticeably lighter than my eGo AIO's...they're noticeably smaller...
So...for me...my filled/charged AIO's will remain on the table by my door...for when I'm headed O & A...

Much less pressure than I use on the button. I guess not all have this issue.
