O’Lights Usual Great Lighting Products.
Really happy with this small, easy to carry pocket flashlight. Carry’s on my Key Rings, and does not fill up in the pocket or on a Key Ring. My first one lasted for years until a cheap key ring swivel failed. I miss that little light and this one was a replacement. The Colors seem more durable on this one. Bright Light, Bright Graphics. Recommended.

Unobtrusive keychain light that gives a whopping 90 lumens!!
I'm amazed that you get 90 lumens out of such a tiny keychain light!! The exterior design is cool looking too. I can't think of a much better keychain light. Uses just a single AAA battery and will be easy to replace when it goes dead. You don't want the hassle of recharging a keychain light battery, imo. All in all, this is a cool, good performing, and inexpensive light that I really like for my keychain.

Nice keyring light with lots of colors/designs to choose from
The Olight i3E is a super compact keyring flashlight that puts out just the right amount of lumens to illuminate the way walking to/from the car in a dark parking lot or searching for a dropped item. It runs off of one included AAA battery and is easy to turn on to its single brightness of 90 lumens with a simple twist of the head. Using a AAA battery as the power source is great because they’re readily available but typically I prefer the rechargeable flashlights and I really like the Olight i1R 2 Pro for that reason and the fact that the i1R 2 Pro has 2 modes (5 lumens or 180 lumens). That being said, I still really like the i3E, they’re just 2 different use-cases. I like to clip the i3E to my jacket zipper pull via a micro S-biner so I have easy access to it if needed and can quickly unclip it from the jacket when I am using the flashlight. Olight releases new designs and colors for the i3E all the time and I like to collect them and to give as gifts so it’s always fun to see what the latest release will be. Keep an eye out for sales as this flashlight goes on sale often and that’s when I typically order to save a few dollars. Overall, the Olight i3E is a great mini flashlight if you’re just looking for something that can attach to a keyring or zipper pull and be easily accessible for finding your way in the dark. The simplicity of one twist for on/off and the use of a AAA battery makes this flashlight a great choice as a backup light or a great gift as well.

Worth it!
Good little keychain flashlight. Great stocking stuffer. It is just a twist on twist off, but it is brighter than you would need with such a little light, and takes a AAA battery. The whole light itself is a little bigger than a AA, so you wouldn’t really notice it in a pocket or anything. Not the brightest flashlight ever, but it is better than an iPhone light.

It is great when something works even better than expected.
Went through a couple of other flashlights like this trying to find a good keychain light and after losing the front lens and the whole flashlight when the back end came off I happened to find this one on a lightning round sale and bought 2 since the price was right. Was I lucky! The size is really great for use on the keychain and I use it almost every night when walking the dogs. The first one has been so reliable that I have not had to touch the second one I bought. The light is very bright and battery is easy to change so it is very dependable.

Excellent for carrying every day
I love this flashlight. For health reasons, I need a dependable, bright, durable, small, very light flashlight to carry at all times away from my residence. This product fills the bill. My first purchase lasted over three years of everyday carry. I rarely have to actually use it for more than a few seconds at a time, so the battery lasts for a year or more. I have it attached to my auto key fob and it is completely comfortable in a front jeans pocket. My second light is going on 2+ years now, and I have yet to need to change the battery. Will purchase again when/if I wear this one out.
