This is a good light by Streamlight, rated at 10 lumens.

Bright enough to light up a room in the dark, will help you find your way in the dark, excellent for finding things in crowded dark places like at the movie theaters or under the car seat. Will help you find a keyhole in the dark.

Attaches to your keys, and you won't ever notice it's there till you need it.

It already comes with its batteries. What more can you ask for?

I woulda given in 5 stars if the light traveled as far as my Photon, if it didn't use those tiny batteries, and if the light was pure white instead of having a "purple" tint to it. However, its a nice light to have on your keychain.

This is a very small but bright flashlight. I thought it would be one of my favorites. However I gave it to my wife to use and she attached it to her keychain as it looks like it is to be used. Only a few hours later we found that the end had unscrewed itself and was gone with all the batteries. Well it was great while it lasted. If you get one of these keep it in a container not on a keychain.

This has to be by far the best flashlight you can carry on your key chain. The light output from it will blow your mind! I can't believe how much light this little tiny thing puts out. More than I ever expected. I am very picky when it comes to flashlights. I am not one to buy an led with 20 of them thinking it will be bright. If it has multiple led's it is junk!

I do not like to carry a bulky key chain. This light keeps that to a minimum. The car keys with the built in remote are bulkier.

As for operation, well all it takes is a little twist. One reviewer said they had to use two hands. I can hold the light in my hand while using my thumb and finger to twist it on. One hand operation seems very easy to me. Less than a 1/4 of a turn from off to on.

As someone who owns other high quality flashlights (surefire) I would highly recommend this as a pocket/key chain type light. You can't go wrong with this purchase.

As soon as my wife spotted it she immediately wanted it on her key chain! Needless to say I had to order another for myself. So, guys if your buying this get two!!!

This small light is fantastic. I purchased 3 of them for my family as Christmas gifts. All of them went to my brother in laws; who are gadget snobs. When they took them out of the packages, they were amazed by the intense light and how small they were. I compared them to my mini mag light and there is no comparison. Buy the Streamlight!

The true success of the light was seeing them on their key chains the next day and not stashed in some forgotten corner.

I am getting one for myself and pawning off the mini mag light to someone else.

I got the Streamlight Nanolight to put on my keychain and it's great -- and smaller than a lot of keys. This is a handy little flashright to have around for small emergencies, such as finding keyholes or paths in the dark: its power of illumination is a lot stronger that you'd expect from something this size, and it is extremely well built and robust. Just a slight twist will keep it on; no need to keep pressing a button. I definitely recommend it.
