KEY SMARTKeySmart Nano Torch - World's Smallest and Brightest Flashlight for Your Keychain

Tiny. Just over an inch long and very thin.Steel. Feels solid and well made in your hand. Slightly heavy in a good way.Bright. Surprisingly bright for it size, but not quite as bright as a typical smartphone flashlight. Seems built to last.Uses Four LR521 179 Watch Batteries. Not sure where to eventually get replacements, as nothing comes up exactly for that in, for example, an Amazon search. (These might work, but not sure:  1.5V LR69 SR521 SR521SW 521A LR521 LR63 SR63 379 AG0 Button Cell Battery 10PC Lastly, I connected this to my keychain without the little included keyring, as I didn't see it when I first opened the package. Then about to review the product, noticed the keyring in the pictures so went through the trash and sure enough, the keyring was still in the package. The keyring is on the back of the package, not connected to the flashlight, so just a heads up because it's easy to miss!All in all well worth the premium price. Enjoy

Very small, has a bright light. You have to turn it many times for it to come on, then can back it off far enough that it doesn't accidentally turn on. I had to rate this a one because I only used it about 3 times and then the light died. I've tried different new batteries and still no light. Extremely disappointed.

Ideal very compact but powerful key chain flashlight. Feels solid, quality stainless steel construction and easy operation. The light beam is plenty bright enough for use with your keys, but I'm also finding other uses, like finding the poop to pick up when walking my dog at night. It's so handy and always available right there on my key chain. A little pricey but is well worth it as it shows you do get what you pay for!

I originally bought this nano-flashlight in March 2018 (for $20) and I hope that they have become much brighter since then. Generally I would highly recommend buying a standalone flashlight instead of this if possible, unless specific circumstances prevent you from doing so, in which case I would buy this nano torch as a last resort and for emergencies only. While seven lumens may seem bright, unless you are in a pitch dark room and need to clearly see more than a few feet ahead, I would recommend a different light altogether. Luckily it managed to save me in an emergency, but since my circumstances have drastically changed I tossed this light about a year later.Personal pros:-Small, light, smooth, responsive and easy to operate. It helped bulk up my keychain (I carry few keys) without adding too much weight, allowing me to easily withdraw my keys from my pocket(s) and remind me of their presence. The light itself twisted on and off and remained off until the next use and the beam constantly remained steady, however this could also be due to disuse.-Sleek and stylish makes it easy to blend in with similarly colored keys.-Came in handy during an emergency at work. For security purposes my employee class was not allowed to bring in much else besides food and the clothes on our backs (especially not electronics) and, having had experienced power outages at work before, wanted something to help avoid similar chaos. During the next outage I led a small group out to safety, bouncing this light off the tons of twisted metal across the sprawling pitch black complex the whole time. Resources could then be freed up to escort others out of the building more quickly, and leaving early (and beating the evacuating traffic) was always a plus. Although I was able to use this torch effectively, evacuating the building (and possibly with more people) would have been much easier had I been allowed to bring in a higher-quality flashlight.Personal cons:-The light is far too dim to be of use outside of dire situations, and even then it will likely be redundant compared to say, phone flashlight software.-The torch itself is too thin to easily locate if separated from a keychain/ring.Overall I would say this nano-torch is more of a novelty than something to rely on. While it is nifty-looking, intuitively easy to use and has a steady beam, the light itself is dangerously dim and the torch is best suited for scenarios in which absolutely no other options for illumination are available. Even pen flashlights or mini flashlights (I recommend McMaster-Carr mini flashlights) are better than this torch, but hopefully these torches have improved somewhat since 2018. Nonetheless, for coming in handy during my specific emergency, I give this "KeySmart Nano Torch - World's Smallest and Brightest Flashlight for Your Keychain" a serviceable 3/5 stars!

On-off function is tricky and unreliable. I find the flashlight “on” sometimes when I remove it from my pocket. Turning off sometimes seems perilously close to unscrewing the battery cover off completely. Batteries are harder to find and a bit more expensive than expected.

This is so tiny, I couldn't believe it! But it's plenty bright and is perfect for finding stuff at the bottom of my purse, or at night on the floor of the car, or to find the right house key for the door lock. It didn't come with any information or instructions at all and at first I couldn't figure out how to turn it on. I looked on the company website but it doesn't even list the flashlight. So obviously, I finally figured out how to turn it on. I'm concerned, though, about it coming unscrewed. I'll have to be vigilant about checking it occasionally to make sure that it doesn't either get accidentally turned on in my purse so the batteries wear out, or become unscrewed and the bottom falls off and is lost, which is what happened to my previous keychain flashlights.

I like the design, sturdiness and compact size of it, but I can’t excuse the poor quality and presentation of the flashlight upon opening it. I have purchased this flashlight TWO times in hope that the first time I just got a dud, but nope. The batteries are held together by plastic and all arrive already corroded. Beware that if you decide to keep this little guy you will undoubtedly have to purchase your own replacement batteries immediately upon receiving it. This is unacceptable. It’s not rocket science to properly package and ship items such as this, so either Keysmart is using old batteries or they need to re-evaluate shipping the flashlight with the batteries already inserted. Absolute fail in their part and incredibly frustrating to be on the receiving end of after spending your hard earned money.

La lámpara jamás prendió y es demasiado pequeña, lo cual sería una queja si en realidad hubiera funcionado, lo cual no hizo. Terrible.

Dimensioni piccole, perfetta per essere attaccata al portachiavi e messa in tasca

Small and sturdy so easy to use on a keyring. The light is bright enough to enable you to see as you walk or open the door etc. Very strong and sturdy.
