I'm not a fan of the ring feature at all. As far as not losing it during a self defense situation, I would rather have a lanyard instead of that finger ring.
I think a torch that has a lanyard as well as a pocket/belt clip is ideal. But I don't think I've ever seen a light that has both. What is everyone's opinions on which would be preferable to have if you had to choose one or the other? A pocket clip for more convenient carry or a lanyard to minimize risk of dropping it and/or having it taken away by your assailant?
Pocket clip.
I don't want a flashlight secured to my hand that a suspect can grab and use to control my arm.
