Water-powered Mini HydraLight! Does it really work?

A few years ago I both bought and reported on the HydraLight Flashlight, the water powered flashlight. Its operation was  not great. Now it's probably the same company that now offers the 3 Pack Mini Emergency LED Water Powered Flashlight. Here's what the company says about them: NO POWER NO PROBLEM: Activates in 15 seconds by wetting the base; no batteries, plug-in or power source required; Flashlights run for 72 hours total; Switch off to extend time with hand light. Perfect for power outages, blackouts, flashlight emergency preparedness. Compact size ideal for pocket, pack, first-aid kit; Take camping, hiking, in auto glovebox, travel flash light survival flashlight. 3 Pack, each one 2.75”H x 1.6”W x 0.5”D. 3/$12.95

Did they work? Sort of. The quality is very uneven & with 2 of the 3 samples, the LED light was not very bright. You can see just how bright in my video. But since the shelf life is said to be unlimited, I do have 3 unused ones standing, since they only about $4. Remember, these are all single use - once activated & the light dies, they're finished!

But wait, there's more!!! Does how much you pay make a difference?

What if you spent 3X the amount of money. Like $12.00 for one, instead of $12.56 for 3? I did that too, by buying the Eton Blackout Buddy American Red Cross version. Even though it had 3 LED’s vs 2 for the cheaper one, it was no better and it doesn't even have an on/off switch. Strangely, the cheaper ones with on/off switches lasted longer in my very unscientific tests. Remember, these are all single use - once activated & the light dies, they're finished! I don't think this is a worthwhile buy, but here's the link anyway.
