Just a comment on the poll. It is dated 10-31-14. Those who responded may very well be the early adopters. They are the ones who went into uncharted water, experienced and discussed the good, as well as, the bad. I did not purchase my first iStick until November. Due to the experiences of the early adopters the water was well charted. I knew exactly what I was getting. There has been no buyers remorse.
The iStick may not be for everyone. For this ol' woman, it is darn near perfect. My fingers wrap around it as if it was custom made and it is very easy to use. It doesn't hurt that it has eye appeal. It is soooo cute.
For ego clearos I use the 510/ego adapter. The adapter fits nicely and I think it looks nice. I screw the Nautilus minis directly into the 510 connector. The instant I feel the slightest resistance from the threads I stop and start over. One person mentioned going the oposite direction to catch the threads. Then, proceeding in the correct direction. It works. When I think about it I hold the clearo so that the clearo threads are kind of floating between the iStick threads. I do not tighten the the clearo all the way to the top of the iStick. There is a gap of 1 or 2 business cards (I measured) between the bottom of the Nautilus mini and the top of the iStick.
I am also careful with the USB port. I have one connector that seems to fit better and goes in smoother than the others. I use that one almost exclusively unless I want to charge more than one at a time which is rare.
I am kind of attracted to the iStick mini but am concerned that it may be too small and thick to fit in the hand comfortably. Again, I'll wait until I see pics and read the experiences of the early adopters, especially the ladies.
FWIW, I did not vote in the pole. At least, I don't think I did.
