Twist to turn on/off, so no button to accidentally get pressed. So no accidental rundown of battery -- simple, easy. Very bright. Small, lightweight. AAA batteries are easy to find and store, so no need for recharging station/cable/lithium powersource. Inexpensive compared to multi-mode alternative lights (and I never use all those modes anyway!). Good choice for a car emergency kit, hiking kit, toolbox, or every day carry. Would definitely buy this again.

Easy to use and pretty bright for such a small flashlight. Nice to have the ability to use AAA batteries. Never need to worry about charging it. I always have spare AAA batteries in the house. It would be nice if it had a battery level indicator but for a light this small and inexpensive it might be a little much to ask for. I definitely recommend it to anyone looking for bright, small and easy to use flashlight

This is a review of the Olight i3E EOS 90 Lumen Flashlight in Black. I am an enthusiast of flashlights and coolers. This flashlight meets my criteria perfectly well: 1) small as possible, 2) bright, 3) lightweight, 4) uses only 1 aa or aaa battery, 5) is waterproof, and 6) has a simple interface.Positives:1. This is tiny, even more so than the Fenix E05 (which was already tiny).2. This is very bright and appears to be about the 90 lumens that it claims.3. This is even lighter than the Fenix E05. This is the lightest AAA keychain style flashlight that I have come across. You can tell by my reviews, I have had a lot of experience with flashlights. Out of all of the AAA flashlights, this is the first that I do not mind having on my keychain, which is a very lightweight setup.4. It uses just one AAA battery, which is common in other things such as your remote controls for the television.5. It has the same o-ring design as other lights in this category with the typical IPX-8 submersible standards.6. It has the most simple interface, just twist for on and twist back again for off! That is my favorite feature of this light. With other lights, 95% of the time is used on the "high" level. All of my other flashlights, with exception of the Fenix E11 which is my favorite light (too bad it has already been replaced with the E12), require users to cycle between multiple brightness levels along with SOS or Strobe modes to get to your desired setting. This is just simple on-and-off.Negatives:- None.Neutral:1. The Fenix E11 is my favorite AA flashlight (and overall flashlight) being the smallest AA flashlight I have come across and it has my favorite feature of a simple CLICK of the button switch to turn on and turn off. This Olight i3E is likely my favorite AAA flashlight as it has just one setting of "high" and has one simple step of TWIST tight to turn on and loose to turn off. Both flashlights have a simple one-step interface. However, I prefer the easier to use (especially with one hand) CLICK switch to the TWIST switch. This is just my preference.Some may argue that the twist switch is more reliable, which has merit to it. Other will say that a click button switch can be accidentally activated if bumped into something, which is possible. Lastly, if this flashlight had a click button switch on it, it would likely be longer in length. Despite all of these points, I have found the simple click is easier to use with one hand and I have never had the Fenix E11 accidentally turn on whether in my pocket or in a bag.I have only had this light for a couple of weeks as of March 12, 2016. It is too soon to determine if this is a reliable flashlight, which will require continued use over time. So far, it has been attached to my keychain, which stays in my pocket or gets thrown into a bag for most of the day. An update will be provided in several months to report on how this light does. Previous experiences with the Fenix E05 has been disappointing as at least four of the flashlights that I purchased (for myself and family members) failed within a year's time. These lights were all replaced with the larger Fenix E11, which all continue to work, as does my Fenix LD20. Though the other lights continue to function well, I must admit that the failures of the E05 really hurt my confidence in Fenix.Overall, I rate the Olight i3E EOS 90 lumen flashlight a 5.0 out of 5.0 stars. It is the simplest, tiniest, lightest, single AAA light around. I use it just about on a daily basis. It is the first AAA light that is comfortable enough to have attached to my keychain, which go everywhere with me.UPDATE June 30, 2016:This is easily my favorite AAA light ever. In addition to the black version that was originally purchased, I also picked up the copper version ($20) and two of the silver versions ($13 each). This should show you how much this flashlight is appreciated. My wife took over the beautiful, but heavier copper one. My favorite is the silver version, which I put in our emergency kit. Once again, this is the simplest, tiniest, and most lightweight AAA flashlight I have owned. Best feature, according to my preferences, is the one setting of full power mode. With other lights, too much time is wasted on finding the desired setting. With this one, you know that there is just one full power mode before you even turn it on.UPDATE July 8, 2016:Attached are some pictures to compare the Olight 90 Lumens i3E EOS in black. A size comparison with the 4Sevens Preon 2 in Green, the 4Sevens Preon 1 in solid Titanium, and the Olight i3E EOS in black. The other pictures compare the beam shots for 3 lights in high mode at a 20 inch distance from a white wall (the Preon 2 on the left, the Preon 1 in the middle, and the Olight i3E EOS on the right). I believe Preon 2 claims 192 lumens, Preon 1 was 80 if I recall, and the Olight i3E is 90 lumens.

Gr8 light but has a single mode.

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 sivous voulez la conserver; elle est si pratique qu'on n'a pas envie de la perdre !Livraison très rapide et emballage soigné, vendeur consciencieux.

For this price the light it has is so good

Malgré sa petite taille .Cette lampe éclaire franchement très bien et je la recommande sans hésiter. Si vous l'accroché à vos clés. Mettre un anneau plus solide l'original est trop fragile.

Product received as described, small but powerful for low light areas, easy can be hooked on keychain.
