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.

Quality flashlight but drains battery very fast and that type of battery is expensive, I suggest to buy AA flashlight instead

Overall good, bright flashlight, one thing I don't like is when you turn it on and off it cycles through the different modes instead of resetting every time its shut off. Plus a " batteries not included " notice would have been nice.

The flashlight is bright it has a focused area that goes pretty far and lights everything close too, it can pop on and off your gun fast, but the on button I think is horrible, I end up turning it on all the time by accident, it needs to be a up and down switch, the button makes it almost unusable in a holster, and it's easy to bump on. I have to wedge paper underneath the button so I can put it in a holster, I would love this flashlight so much if the on switch was better. I would tell someone to try to find a better switch on a flashlight before buying this one. But I like that it has strobe which seems pretty good, this flashlight is brighter then my cree q5 $4 flashlight or the same need to test with a fresh battery. Don't underestimate that $4 flashlight it's bright

I used this for a few days and sent it back.

I would have kept it and recommended it to everyone who loves great flashlights if:

1. the switch was a push button at back end of the flashlight
2. when turned on, light would default to the last setting used

The twist-like-an-old-AA-Maglight switch is okay but not for an expensive light like this and NOT when you have two useful settings (med and high) that have to be scrolled to by screwing and unscrewing the front of the flashlight. Might have gotten used to it but it would never have felt good so I sent it back instead of having to deal with this annoyance.

The flashlight is good. The thumb switch is a bit weird. You click it firmly to go from OFF to ON, or ON to OFF. However, you have to just touch it after it is ON, to cycle the different brightness settings... it just feels weird and often gets you to the wrong brightness.

This is a nice flashlight with 5 different brightness.  The charger also nice.

I take a star off because I just spent over $100 on a flashlight.  I know good things cost money, but that's a lot of scratch.  Hope it last a long time.

As other reviewers state, I don't believe this is a 1,000 lumen flashlight and thought going into it that a 400 lumen flashlight for the price was a very good purchase.  There are too many modes to cycle through.  I would prefer a high and low beam as I cant think of when I have ever needed a strobe - unless it was to dance at some sort of club 20 years ago.  The battery does not fit well in the housing and as a result, it jiggles and the light is intermittent.  So long as you don't jostle the flashlight, its a very good and powerful back up light that I keep by the back stairs.

Firstly, let me say the clips are awesome. They hold the flashlight in place very well. The lens are okay. The red is so dark, you can hardly see anything with it on. Not sure what the blue one would be used for, but at least you can see with it.

The flashlight is great and I love the durability and light weight form. Only issue I have is that the flashlight description lumens is off by like 30 lumens

The flashlight was the best quality flashlight that I found for a 3-4 year old. It comes with a lanyard as pictured. The on switch is a rocker which a 3 year old can operate. It also has a push button where the light turns on when it is depressed and turns off when released. The light is bright enough for a child but not too bright and does not heat up.
The only problem is that once the battery runs out and you change the battery, it does not work again. I have purchased three of them and they all have the same problem. I will not buy again.

The first thing that caughts one's eye when looking at E2D are the heavy "teeth" around the bezel and end cap of the flashlight. The purpose of these teeth is to facilitate using the flashlight as a striking tool or nerve point manipulation instrument, much like Kubotan. The flashlight is designed to be sturdy enough to withstand the impact forces if used as a striking tool, for example the tempered glass lens is extra thick.

The body of the flashlight is somewhat small, in fact it can be too small with persons with large hands. In that case the teeth in the end cap can dig painfully into one's palm. The flashlight has a removable pocket clip, and that's the way it should be carried. If using a holster, the slimness of the flashlight can cause it falling through the holster, if it's open at the bottom. And in any case, the teeth on the end cap make reholstering the flashlight a bit difficult.

The light switch has no momentary on function (it's a click-on switch), but if operated with the thumb partially on top of the teeth of the end cap, the light switch won't depress so much that it will click on. However, that way the teeth can bite quite painfully into your thumb. Not having a momentary on light switch is a serious drawback in a flashlight intended for self defence appilications The light switch has a lock out function, preventing accidental activation if carried inside a pocket, for example.

The light beam of the flashlight is calibrated so that it is very bright at short ranges (under ten feet), but the intensity of the light drops quite dramatically at extended ranges (say, over hundred feet). The intensity of the light beam can match quality tactical flashlights only at very close range. Therefore this flashlight is not suited very well for law enforcement or other security trade professions. It's a good flashlight for it's intended purpose (self defense), but by far not the best I have seen.

I received this item. First thing I notice was there were no instructions on how to use the item or what kind of batteries The CrazyFire C8 LED Flashlight took. So it takes 2 CR123 batteries. This flashlight is made of high quality aluminum alloy. The CrazyFire C8 LED Flashlight is a well built flashlight. It has at least 4 or more levels. When you push the flashlight on, just tap the on button and you will see all the different levels of light. The CrazyFire C8 LED Flashlight does put out a lot of light. I wouldn't recommend facing it towards your face because if your eyes are sensitive to light,  it will affect you The CrazyFire C8 LED Flashlight does delivery as for as the light goes. This is also a waterproof flashlight. I gave it  4 stars because of no instructions and it requires the special batteries. This is a good quality flashlight. I received this flashlight at a discounted price for an exchange for my honest review.

The quality of the light itself is excellent, but the quality of the flashlight leaves much to be desired.  I fell in love with this light when it arrived.  The small size is easily portable, which is nice.  The problem is that after minimal use, the light began to dim and now switches to the dimmest mode essentially whenever it's touched.  They could have done better.

The E2 on the left is my favorite flashlight.  Fit perfectly in my hand. The switch is easy to turn on and off with my thumb. The E2 uses one AA and it is bright.  The switch can dim the light in a continuously fashion; not in step.

The HP1 on the right is a little bit brighter using the same AA battery.  I don't have any 14500 to try.  The HP1 can zoom and focus. The two stars is because of the switch.  It is small and it is placed inside the barrel.  The switch is tight and stiff to push.  The barrel is too small for me to turn on and off with my thumb.  I need to use my finger to poke the switch to turn it on and off.  My finger gets hurt after poking the switch for a while. The switch is very stiff.

If you need to use a small flashlight all day, find another one.  The switch is bad.

This is a great flashlight bundle. The flashlight is very powerful an has great reach. The deal breaker for me is it's very large for a flashlight and quite heavy. It comes with a shoulder strap but they don't provide enough hardware to attach it to both batteries. This flashlight definitely won't fit in your pants pocket so one hand is tied up carrying it half the time. Also Nitecore's tolerances on this hardware is very poor. Impossible to install without tools and once installed it can't be removed without damaging the finish. By the way instructions failed to mentionon how to install shoulder strap hardware. It's intuitive but because of the improper tolerances you might think your doing something wrong. Seller responded to my email promptly but unfortunately according to the seller a second shoulder strap ring and clip can not be procured from Nitecore, disappointed that they aren't able to solve this issue for me. I emailed Nitecore and they requested more information which I have sent. I'm willing to pay extra for the hardware it just doesn't seem available, apparently the necessary mounting hardware is not included with nbp68 battery (very stupid, it's really necessary for this flashlight).

I'll keep the flashlight because of the quality but unfortunately I'm only going to be using the nbp68 battery pack unless Nitecore sends me the mounting hardware, the 18650's will be for emergency use only. Maybe I can make my own mounting hardware, but I shouldn't have to.

I will update this review if this issue gets resolved.

This light has a lot of good qualities.  The anodized aluminum casing is solid and the endcap houses the switch.  It conludes full-on and momentary mode and it's pretty hard to accidentally leave it on.  The LED is quite bright and runs well on the 3 AAA batteries.  I like that it uses easily replaceable batts for emergencies.  The triple As fit into a plastic insert and this is about the only thing that worries me about it's construction.  The LED itself sits behind a thick clear plastic "lens" that helps with the light dispersment.  Seems to run for quite a long time on the batteries while maintaining it's brightness.  It has a decent throw, at 40' it's very useful and it's still okay at 60-70'.

All in all, quite solidly built and I've had no problems.  It's a bit pricey, but seems to be of good quality.  The o-ring on the back cap was broken, so had to be replaced, but I guess I can live with that.  Mine came with a decent nylon sheath (better than most flashlight sheathes I've had), though I don't know if the model on Amazon has it included.
