The flashlight has a tendency to go on by itself , during the jostling in your pocket.  Therefore be prepare to replae battery more often than naught.. It does with 4 LR 41 batteries encased plastic. I am going to have to but 4 LR 41

I've had it for a few months. It is quite small, yet outputs 300 lumens.
I'd recommend it to someone that is looking for a little flashlight.

The low power light doesn't come on when the battery (it only uses a single battery)
is low. The flashlight still worked, but I only realized the battery was on its way out
when the turbo setting wouldn't engage. Other brightness settings still worked.

THE LIGHT IS VERY BRIGHT. THE MOUNT IS WELL MADE. THE MATERIAL OF THE FLASHLIGHT IS GOOD QUALITY; HOWEVER THE SWITCHES ON CAP AND CORD ONLY HAVE AN ON AND OFF (OPEN AND CLOSE POSITION). IT IS NOT CAPABLE OF QUICK BURSTS OF LIGHT. JUST A FEATURE I WOULD HAVE OF EXPECTED FOR THE PRICE. IF YOU MAKE A TACTICAL LIGHT YOU MUST THINK OF THE SAFETY OF THE USER. LEAVING THE LIGHT ON TO LONG MAY CAUSE NIGHT BLINDNESS. SOME MAY THINK OF THIS AS A SAFETY FEATURE PREVENTING ACCIDENTAL BURSTS OF LIGHT.

On my key ring, it turns on by itself sometimes. So the batteries wear out frequently.

First off, great price, loved the size of it, solid power and I'm a fan of the adjustments it has. However, after about 8 months of only occasional use, the flashlight adjusts the brightness or flashing on its own. I've tried changing batteries, lightly taking it apart for connection issues and I see nothing. Now, when I walk the dog in the morning I either look like I'm lighting a walkway or that I'm going to a rave at 6am.

Brightness is pretty good & the flashlight itself is really heavy duty. I just wish the strobe came on on the first click. I got this for self defense & I'm pretty sure if someone tried to attack me I wouldn't have time to click the thing 5 times to try & impair their vision & get away. It's a good flashlight though, I would buy it again just not what I was hoping for.

This is a TINY and powerful for it's size little key-chain flashlight.  My only gripe with it is how it turns on/off.  You twist it as tight as it will go to turn on, and back it off a little to turn off, and continue "unscrewing" to disassemble completely to change batteries.  My issue is that I think it would be easy to accidentally turn it on and in a bright setting you may not notice it until the batter is dead.  I also feel like it would be easy to accidentally unscrew it to the point that it falls apart.  I just got it today and haven't experienced those issues yet but I feel like it could happen.  I would prefer some sort of on/off switch or button.  Otherwise for the price and size it's great.

The stunner function seems to work OK.  However the flashlight only works intermittently, possible because of a defective three position switch.

The flashlight is a great little pocket flashlight. I havd a friend in law enforcement  who uses it for work carry, as it's  the perfect size for shooting at night with using your support hand for the light. (Back to back hold or something like that)  Anyhow, the only annoying thing is the strobe effect, which I cannot figure out At All. It seems to be related to how long you hold the switch down.

I love this light when it decides to work. At first, it worked great and I loved everything about it. Now I can't get it to turn on half the time and when I do it likes it turn off on its own. I was out night fishing with it one night, I charged it fully before. about an hour into the trip, the light decided to start its antics for the first time. I was lucky that I had a backup flashlight in my bag or I would have screwed.

This is an excellent flashlight for the money nice and solidly made bright light but unfortunately it switches to flashing mode far too often and you have to turn it on and off again to get it back to a solid been other than that it's a wonderful flashlight if I had to buy it again I would just do the single option flashlight not the double option with flashing light

It appears to be as advertised, and do what it was advertised to do. I haven't had to use it, so I have no clue how it would stand up under an attack situation. It might just produce a sense of security, although it may be false. The flashlight sure is bright!!

Seems to work well. for some reason I expected it a bit smaller; you don't really keep this in your coat pocket (not complaining, just explaining; higher capacity is always larger size).

Turning on the flashlight would have been easier with a button; you always need two hands to turn the head to turn it on. The rubber stop does not stay in - at all. I guess you can just leave it on, but that may get dirt in the connectors.

The flashlight is very hard to turn on.  You have to press it in really hard (until it clicks) in order to turn it on and off.  It hurts my fingers to do this.

This 3 1/8 long 1.8 oz aluminum flashlight from AUFO comes in a silver metal tin with foam inserts. Pretty nice for a small portable flashlight. If only it didn't have such a wonky power switch.

Upon opening the tin, you are presented with the flashlight, a generic AA battery but no instructions. You must be thinking, how difficult is it to work a flashlight? You unscrew the barrel to insert the battery, but I was looking for the switch. No joy. To power it on, you have to twist it to a certain point. I found that a bit strange. To switch between the three modes (high, low, flash) you screw it a little to engage and then loosen to turn it off. You can also leave it almost on, and then push the top down to engage the light. It comes with a nice clip to attach to a key ring.

The design is waterproof and the light is very bright for such a small light, but will loose a star because of the weird power on options.

When new, this light does when it is advertised to do. The red light is dim, but perhaps enough to walk down a dark paved sidewalk without ruining your night vision. I have no idea what the green light is for. The white light is not the brightest, but OK for a small inexpensive flashlight.

My biggest complaint is the hard plastic case to this flashlight. I bet that dropping it on the ground will destroy it, unlike the metal flashlights you can often find in this price range. And that click open battery door is much less robust than a screw-on battery cover. Fortunately, this appears to be a closeout item and you may be able to find it at discount stores for half the price that Amazon is charging. Shop around.

This is a great flashlight, compact and easy to carry. It seems pretty durable as well, though I haven't had the need to test that yet. The light is particularly bright, especially when the end is extended. I like the three modes (bright, dim, and strobe) however the one thing that I would change is the fact that after you turn the light off, it will advance to the next mode the next time you turn it on - so if you turn it off when using the dim light, the next time it goes on it will be in strobe. I find myself needing to remember to click the light three times before turning it all the way off so that it will be in the mode I want next time (very annoying turning it on and unexpectedly being in strobe light mode). If not for this, I would rate the flashlight at 5 stars.
