    For some reason small key chain lighting systems have rarely met my needs or, if they did, would disappear from the market because of some sort of business failing. A lot of rechargeable keychain lights used non-rechargeable batteries, had limited power management, often came on in your pocket leading to comments like “I guess you’re glad to see me….” On the other hand the keychain light that had the best of both worlds would ultimately fail because they were bought by their competitors and taken off the market. The E03R is a little light that does a lot. It is durable, rechargeable, has variable brightness control, and a “bright”, actually usable, ‘red’ mode – excellent for night work when you want to preserve whatever night-vision you have. If I had a complaint it would be the light doesn’t go directly ‘red’ without going through the white light phase. This is a minor complaint and this is easy to work around. For the price it is a great gift idea. Especially for old goats, like me, who sometimes struggle to read the bar tab in low light. Based on experience, I would buy several just in case some ‘smart’ manager at Fenix decides to discontinue the E03R and replace it with a 12000 lumen headlamp.

    I am very pleased with my purchase! My E03R has already on my key chain and has come in handy, when I needed it. It’s exceeded my expectations and will always be part of my EDC. My wife likes the convenience of the E03R, instead of having to rely on her iPhone flashlight. It looks like I will be making another purchase soon!

    I picked up a one of these, and ended up buying a second one for a family member too. This light is AMAZINGLY tiny…small enough that I actually keep this light in my pocket all of the time and often forget that it’s there LOL. The brightness is impressive, and I’ve found the red light to be extremely useful when trying to navigate at night without blowing up my night vision or waking up my wife or dog. There are times when I wish it had a direct to turbo mode and direct to red mode (it quickly flashes past the low-white setting to get to red), but the trade-off of it’s size, thin shape, and battery life are totally worth it. I highly recommend this as an EDC or keychain light!

    Ok…. this light is small, REALLY small. I could put it inside a tic tac box and still have room to spare! The C-type charger is super convenient, and allows for a pretty fast charge. But the 260 lumens that this bad boy kicks out is the real show stopper! So put your phones away… the E03R has a lot of light for such a small package, and more than enough for whatever situation you might need it for. The lock function is also greatly appreciated to avoid those pesky accidental turn ons that can drain your battery life and leave you high and battery-dry at the worst times! Never be without a light anymore, throw the E03R on your keychain and have a little peace of mind!

    A great compact torch, my new favorite. Brighter at its highest setting than the (many) others I’ve owned at this size and with a solid metal body that feels like it can take the rough-and-tumble of everyday use. I like the red low-light option as will.
    One suggestion to consider for future version: a triple-click strobe would be a nice addition.

    Spent more money on a Nebo when they first came out. Died shortly after and the finish wore off quickly.
    I like the Fenix design better and it is easier to use. USB Type-C is a wonderful touch. So far the sharper edges are wearing slightly but it takes a beating on my key ring. The charging cover is easy to remove and the flush button keeps it from accidently turning on even without the lock on. Needs to be able to go directly to red if your using it on and off in the dark. Much quicker to get to than my phone flashlight.

    Excellent little light. The convenience of USB C, the small form factor and the reasonable lume levels are great. The low level (5 lumens) is enough to navigate the house at night, and the red light is a great addition if you need to minimize disruptions. Haven’t tried it outdoors yet, but should be enough as a keychain light.

    I keep this flashlight on my key chain and absolutely love it. Incredibly bright white LED, less bright but awesome additional red LED. USB-C charging is a huge plus. My only complaint after carrying it every day for about three weeks, is that the gray finish is starting to wear off on the edges of the light. It is on a keychain with metal keys, which is a given for a keychain light. I don’t expect the finish to last very long at all, but I’m okay with that. The purpose of gear isn’t to look nice, it’s to be functional. I would definitely recommend this light to someone who wants a well designed, high output light in a tiny form factor.

    First of all, shipping was fast. The flashlight itself is one solid block of metal, which feels extremely solid and well made. I really like how the light always cycles from low to high, and activating the red light is very easy. These two features help preserve night vision. Battery life is pretty decent I only had to charge it twice, including the initial charge, since I’ve got it 2 weeks ago.
    I highly recommend it for aviation use. I just wish they make a wrist band for it so I can wear it like a watch. Fenix, hope you are reading this!!!!

    Way smaller, way brighter than expected. I was expecting a flashlight that was approximately the size of the keyfob for my vehicle, but it’s actually about half the size. What a pleasant surprise. I’ve carried it around with me for about a month now, and unlike other reviewers, I haven’t yet had the light turn on by accident.

    It charges with USB-C port, which is perfect.

    I took a few photos to show how much brighter this is than the LED light on my phone, but it really wasn’t a fair comparison. It’s in a completely different class of light. As a home inspector, I was turned on to the 258 lumen Fenix TK11 back around 2008 or so, and I thought it was the greatest thing ever, compared to the huge flashlights that I used to use. I’ve moved on to bigger and better flashlights since then, but I still have my TK11, so I pulled it out of retirement to take some comparison images with the EO3R. This tiny little keychain light kicked the butt of what used to be my primary work light!

    This would make for an awesome stocking stuffer.

      Please note this light does have a lock/unlock feature on it that will quickly unlock the light and immediately put it into low mode:

      Lock: with the light switched off, double click the switch to lock the light, the light will blink twice on Low to indicate locked status.
      Unlock: with the light locked, double click the switch, the light will be unlocked and activated on Low.
      In locked status, clicking or pressing the switch will activate 2 one-second blinks on Low to indicate locked status.

    Received mine last week and I love it!. Super light and bright. It blows away the prior AAA light I was using at a fraction of the weight and size. It’s so small and light you won’t notice it on your key chain. The red light is a nice addition for reading in the car or in a darkened place where a white light would attract attention. Construction and finish is top-notch. I’m not sure what happens when the battery stops taking a charge but hopefully that’s a long way off.
