Thanks, Glock-A-Roo!

That particular dogtag mirror seems a bit small (<2 inch^2 of stainless steel) and heavy (1.4 oz) for my taste, and I'd like to see a better aimer on it, but if the stainless steel is flat and clean, 10 mile naked-eye visibility under good conditions seems right for a 2 sq inch stainless steel mirror.

I do like the idea of the integral protective cover for the mirror, and the small size is a help.

There's an advertising page for the mirror here with a 7+ minute video and lots of photos.

I'll order one for some testing. Has anyone else tried that mirror?
