I have always used Eddie Bauer keychain lights. They were a good quality, but over time they'd stop working or the parts would fall off. This thing is tiny, but not too tiny. I decided to remove that branded tag and keep it on my keychain. It's really surprisingly bright!

I needed a small flashlight for those middle-of-the-night excursions when I needed to find something in the dark - something with a noiseless twist-on feature and that wasn't terribly bright.  This little light fits that bill...and then some.

The LED bulb is rated at 10 lumens, but the bright white light that it provides puts my old Mag-lite Solitaire to shame!  Not only does the light it provides seem about 10 times brighter than my old mini-light (without being overly bright), but it lasts much longer per battery change - I've had mine for a year now, using it several times a day, and I'm still on the original set of batteries.  It provides a decent amount of light from such a TINY package!  The flashlight itself is just under 1.5", and it's just under 2.5" in length with the included clip.

I've hung mine from an under shelf tea cup hook in a convenient location, that way it's easy to find it in the dark and replace it when done.  I have dropped it several times and it keeps right on shining.

Deceptively small, but incredibly useful.  I've paid similar prices for larger flashlights, but they've never functioned as well nor offered the usefulness that this little light has.  This would make a -great- keychain light, or just a cool little pocket light.  If you've ever had a need for a small flashlight, the Nano Light will certainly fit the bill.

By far the best small key light out there - and rechargeable too!  Highly recommended.

This flashlight is smaller than a pinkie finger, relatively water-proof, durable, and incredibly bright for its size.  Mine has been running on the same AAA battery I put in it over 6 months ago when I first bought it.  I liked it so much, I got one for my wife.  This little guy is perfect for anybody who likes having a reliable light source on their person. Just slip it on your keychain.  It's the one thing we all carry more than any other day to day item, so you'll always be prepared.

Brilliant, usable output from a single AAA battery. I actually carry this light everyday, it is small enough to fit in a coin pocket and the knurling is pretty resistant to scratches.
There are brighter lights this size, but this works for all of my needs

If I could I would give this flashlight 10 stars. This things is TINY, about the same size as all my keys. But it is perfect size to keep on a keyring and it is VERY bright, lights up my entire hallway at night (30ft long, 4ft wide). It feels very solid, and the color is perfect. Word of advice, if you receive your flashlight and it seems very dim, almost like the batteries are dead, open up the battery compartment and let the batteries sit out for a couple seconds. Some type of oxygen absorbing batteries come with it, after doing that, the flashlight really came to life. Worth every penny.

Great little reflector, cute, lightweight and unbelievably bright! It easily attaches to a jacket, purse, backpack, dog leash, etc. and while secure, can also easily be moved as needed.

Small, bright and useful. This thing is tiny so don't be fooled. It fits perfectly inside my left front pocket and at times I can't really tell it's there. I would give it 5 starts if it came with a case. Other than that it does it's job, it locks and it adjusts. Also when not in use, the light can be flipped over so the bulbs are not exposed.

If you have a limited amount of storage and are in need of a good light, this is perfect for you. I carry around enough crap in my toolbox and have no space leftover. This is smaller than most everything else in there. It is truly usefully bright and with the twist to turn on, it doesn't get bumped on accidentally so I don't find the battery dead when I need it. The only issue I had is I felt it necessary to put a larger key ring on it that I could slip over a finger to prevent me from dropping it accidentally into the equipment I work on.
I was so happy with this tiny flashlight that I have bought more for keeping in glove compartments and my purse.

This little mini keychain light isn't just adorable. It's extremely tiny, lightweight, powerful, and easy to use. You'll hardly notice it's there, but you'll often be glad it is when you clip it to your zipper pull or keyring. I have two mini-flashlights, and this one is almost 1/3 the size of those, but just as bright! I just wish these came in green!

Wow!  This is SO BRIGHT and yet small enough to fit in your purse!  And it is a good thing to have in your hand at night when going to your car, or at your bedside, not only just to see, but it could be used as a defense if you feel threatened , to blind an intruder !

I am very happy that I decided to pic up this small little light. I do have a primary light that I keep on my key chain but I still have found many of uses for this thin card style light and find myself using it much more than I thought I would. The reason that I like it is because my primary key chain light is rechargeable and I have found myself a couple of times caught with it completely dead and that's where this card light came in very handy and saved the day! For me I see is as a very reliable, lightweight, quality back up light option. The batteries are not only included but they are also installed which makes this literally ready to rock as soon as you open the package and press the power button!!! I have a smaller maxpedition velcro wallet and it fits in a regular credit card slot with no issues whatsoever. As per some of the other reviews, where the power button is there is definitely a bulge from the guts of the unit. I personally do not find that to be an issue likely because of the style of wallet I have but even though, if people really do not like iti n their wallet in can easily fit in your pocket and you likely would not even notice it in there. Again, let me emphasize, this is a back up in case of emergency and in case your main lights fail type of item. For what its meant to be I cannot find any issues with it. For all of these reasons among others I have absolutely no issues whatsoever in giving this item my stamp of approval. I definitely recommend this credit card thin emergency pocket light.
I received this item at a discounted rate in exchange for a fair and honest, unbiased review.
