At $3.75 ea? Bargain. Beats most any filament-bulb elites of yesteryear. Lotta stuff in there for price of half-a-cup of coffee.
No programmable niceties (as might ration the juice a bit--should one be Really Lost in the outback). No es una problema.

The zoom feature is handy; normal spot-size and intensity will tell you what you want to know about where you're walking; zoom (to an image of the LED, in focus!)
and you can discern colors, see detail, over a rather small area but adequate to ID things.
Small, light enough for tiny pockets, so even if you have a more heroic model--this one is no burden.
Probably a good Solstice present as anyone can 'need' it ... if you order soon.
