When this showed up is was even smaller than I thought. When you try it, you'll be like...how does this put out so much light??? You twist to actuate the light, making it unlikely to illuminate accidentally in your pocket. The included clip is perfect as well. You can easily remove the light from your keys if you want with a simple push of your thumb...and return it even faster with a simple click. Everybody I've showed it too has loved it. I had to buy 4 more 1 for my wife and 3 for the kids. It rated for 8 hours, seem short right!, BUT the use for this item...a quick light to see a knob, something dropped getting out of the car, or looking for the item that fell out of your pocket at the theater...it takes a while to get to 8 hours. Buy now and buy a lot!

Light is amazingly bright. Too early to tell if the light will stand up over time.

amazing flashlight small and extremely powerful hangs out wherever you need a bright light. I keep it on my coat zipper.

This is a fantastic tiny flashlight that takes up such a little amount of space. I don't like to carry a lot of stuff in my pocket and this doesn't add much. Even though it is only 16 Lumen, that's a lot for such a tiny device. It's much easier and handier than a cell phone light.

My first real use of this was to walk back to my truck, a half mile along the beach at night after taking twilight photos. This was perfect to see where I was going.

I didn't expect such a small light to pack so much punch. Amazing! Smaller and brighter than I had imagined.

Will order more, they make great gifts too.

When I got this is was like half the size I thought it would be. But that made it perfect the for my key ring. To activate the light you have to twist the back end where an O ring is located making it very unlikely to turn on in your pocket unintentionally. For the size it is crazy bright. I got it from deal of the day but if this is something you want it is worth the normal price.

I purchased this flashlight for a friend of mine. It's really tiny, weighs hardly anything, yet the brightness , for its' size, is pretty unbelievable. It really lights up an area.
It runs on four batteries which are included with the light. A package of four replacement batteries are available at B & H for $400 plus tax.
I suggest you purchase this flashlight if you're really looking for a micro sized light weight flashlight .

Awesome bright, tiny light.

I took a chance on this one and I'm glad I did. It is smaller than I thought it would be and a lot brighter than I thought it would be. Highly recommended if you need a bright light in a very small package.
