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.

THESE LIGHTS RULE!!!
We do towing, these babies are great cuz they are small enough to hold in your mouth, yet powerful! I've bought probably at least 10. Every xmas my guys get 2 more, I've bought them for everyone in my family! Also great cuz u can keep them on your keychain, sucks when u need light and have NONE! Batter life is great!

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.

Mighty light barely bigger than a AAA.
I have bought maybe six of these, and the two oldest have burned out after a lot of use. The others are working just fine, and are so incredibly tiny and useful I will probably buy more for the glove compartments and kitchen drawers. One brightness, but it makes up for that by being tiny and light, and solidly built. Very basic but very functional, and at 10 dollars a solid buy. Do note that the Olight store on the web can have sales and a wider variety of colors!

Very impressive for it's size!
For everyday carry, I much prefer the on/off function of a flashlight to be controlled by turning the "head" of the light, as opposed to a click button somewhere - it's much less likely to turn on by accident and this one does that. Geez, this thing is incredibly bright, especially considering just how small the flashlight really is! Although, it's not as bright as a 2 cell LED Maglite is, it's more than bright enough for most casual users. I've already changed out the key chain ring for a larger one, because I like to be able to use one of my fingers to hold the light, as opposed to holding it in my hand. For $10, this is an amazing little light, and really hope that it lasts a long time!

Une très petite lampe d'une puissance étonnante pour sa toute petite taille. Construction sérieuse et finition parfaite, autant que la qualité de la lumière qu'elle fournit. Seul petit bémol, la solidité de la partie porte-clef qui semble vraiment juste. A revoir si vous voulez la conserver; elle est si pratique qu'on n'a pas envie de la perdre ! Livraison très rapide et emballage soigné, vendeur consciencieux.
