I think whether it is “practical” or not depends on the person doing it. This certainly varies from person to person. One ‘size’ does not fit all.

For me, and I suspect some others; while certainly not as easy as a conventional tailcap: it is not a big deal.

I took your challenge & tried it in a totally dark closet. :+1:

First time was 90 seconds (+ or - a couple). Used the end of a fingernail file on a pair of cheap nail clippers.

Second time was 74 seconds (+ or - a couple) using a spoon.
practice makes perfect :wink:

So the practicality question is not an issue for me at all. For some it would/might be.

In addition I doubt I’ll ever use this light in a situation where I have to change batteries in the dark. But… if I do, I find it easy enough to do.

ymmv
