Do fiberoptic (no battery) 'bore light' refracters work?

[gidaeon]

Are these a gimmick or do they do the job? Got a Numrich order and saw these were under $2 and I need a bore light.

its good for quick checks. but i wouldnt do any close examination with one

might as well pay alittle more and get the real thing. missing a hairline crack down the inner wall of your barrel wont make you feel very good about saving money

They work just great if you have a good light source shining in the end so you have some light to refract.

Outside in the sun they will dazzle you.
Not so much on a gunshow floor with dim light.

I have one laying on my workbench all the time & use it.
But I also have a 48" florescent shop light hanging right above the bench.

All of the above.
If you got to have the coolest try this.

Since numrich is so good about still providing shipping codes on their phone message, I ordered both the little fiber optic guy, and a more traditional (if bulky) led flex lamp.

I do like that niteize product that would fit over my old reliable little Mag
