ULTRAFIRE5 Pack SK68 Tactical and Small Flashlights,7w 3-Mode Pocket Torch Adjustable Focus Zoom Light Lamp

I have been buying these since they were first being sold with a inferior LED than what is available today, and first offered many years ago, maybe 12 years or so, can't remember. Unfortunately, over that time I have lost a few of them, but have only had one fail, and it was after being dropped in the salt water and not retrieved after sitting 5 feet deep for around 5 minutes, and it actually didn't fail until a week later or so later. They are not advertised as being waterproof, but several tiems I have briefly submerged them with no issues. Other than that, these things are virtually bulletproof. Not once has I had a switch failure. I carry one with me all of the time, along with a very small Nitecore light on my keychain. Used with a Li-ion battery, they are brighter than I have needed, and the zoom feature incorporated in them is just remarkable, projecting more than 1/4 mile, which complements the Nightcore perfectly. This LED is almost too powerful for the body and the battery, as it will get warm quickly on high power and at that setting will drain a 14500 Li-ion very quickly, but considering the versatility, ruggedness, and super cheap price of these things compared to other options make these a no brainer in my opinion.

Perfecto por el precio.

I keep an ample supply of these little flashlights on hand in every room and every emergency bag. Perfect size to go everywhere and only need one AA battery. Worked beautifully during an ice storm when we lost electricity for 6 days.

Todas funcionaron bien, luz muy brillante como toda lámpara de calidad

The Ying:All good so far. The flashlights appear and function as described in the Amazon ad. I tested with a fresh AA high-quality battery and they appear adequately bright to me, although I cannot confirm the advertised lumen output. They seem to be quite sturdy and I did not find the zoom head to be loose when extended, as was written in another review. (Perhaps that customer received a bad shipment or wrote the review in the wrong product page, IDK.) Though I am not an expert on the UltraFire brand, all the packaging and items I received had the UltraFire logo and trademark and the documentation referred to contact them if necessary and included their name plainly in the web address "ultrafire". I feel these are a great value at $3.06 each as in the package of five. If these were made in the U.S.A., I might pay up to $5 each for these in order to support a more local economy. I might buy more later for gifts.The Yank:No big complaints really. The dimensions are as described, though I would suggest two improvements: extend the length of the metal body approximately 0.5 to 1mm at each end. The reasons are as follows. 1) At the head, the convex lens protrudes in line with the tactical head. So the lens would be better protected from scratching or other damage (such as when standing it on end) if the metal head were slightly proud of the lens. 2) At the end with the toggle button, the button protrudes slightly proud of the metal ring around it, so the flashlight is not very stable when standing on that end. I will update my review if I find any adverse issues.
