Is it a feature or a bug?
depends on point of view
All twisties have the momentary On feature, when pressing the head towards the body. Unless it is unscrewed farther than the play in the threads.
Occasionally someone will discover this, and post about it, as a cool new momentary On feature, they discovered on their twisty.
I just tested an i3e and confirmed it also has the head press for momentary, feature/bug
I usually test my twisties, to learn how far to unscrew them, to avoid the momentary On feature. And I occasionally confirm by pressing on the head, to make sure.
I discovered the feature one day with a nice copper maratac aaa in my pocket… I guess my pants were a bit tight, cause when I crouched down I saw a flash of light from my pocket…
I then went on to document the feature on a Fenix E01, world famous for “reliability”… I wont bore you further with a video of an i3e… trust me…
Twisties have a momentary On, “feature”, that Bugs me. I know how to work around it. All lights have pros and cons.
Some Twisties win at being very small. I like small, and the i3e is my smallest AAA
The Low CRI i3e makes a good spare AAA battery carrier, for my High CRI CuTools…

Momentary ON, is basically caused by slop in the threads… check for yourself by removing the O ring on a twisty… you will discover threads are not a close tolerance fit. The feel of a twisty depends more on the O ring fit than the threads fitment tolerance.
