I wear this light on the shoulder of my vest and it works great. I find that I don’t have to use my handheld flashlight nearly as much. It’s very nice to be hands free with a light whether I’m standing or seated. The battery life is nice and it’s easy to charge afterward. It gives a green light when it’s completed charging.

I've had one of these for over a year now (EDIT: Correction - Just under a year). It's a very bright and convenient source of light to have around with the work I do. It's served me quite well during my time with it. The adjustable head and clip make it very handy as a makeshift headlight: I can clip it onto the bill off a cap or something else thin and direct it to where I'm working. Otherwise, it's small and light enough to be placed in a multitude of locations where a traditional flashlight would have difficulty staying put or even getting into. However, it recently started acting up. It turned on once without me doing anything. I know I've accidently bumped the buttons before, but this time it was literally just sitting on the desk charging and suddenly turned on. Before that incident, the white LEDs would flicker. Pressing the buttons might flicker both sets of lights. Eventually, it stopped functioning at all, just flickering the lights for a moment when the buttons were pressed. As I liked this flashlight quite a bit, I decided to get another one to replace the malfunctioning one. Once I got the new one, I could dissect the old one with concern. If I could fix it, I'd just have two lights. For the cost, it's not that bad. Well, I opened up the old one and found out something was corroding the contact pins on the main IC inside the flashlight. I'm not quite sure if it was electrolyte (doubt it since this is a lithium-ion battery) or more likely just moisture. (I wouldn't be surprised if it was just humidity condensate given the weather where I live.) The corrosion was starting to short the IC pins, causing the issues I witnessed. Some scrapping and cleaning got the flashlight back to normal and fully functional again (mostly; there's still a momentary flicker on button presses for now, but at least the light works as intended otherwise.) If anyone else is have a flickering issue, it could be a simply fix: Jeweler's screwdriver (#1 & #0 Phillips) and a toothpick with maybe some pure isopropyl alcohol should be all you need. Anyway, four stars overall for this product. One star knocked off for the lack of weatherproofing, either by having a fully sealed case (which would likely bump the price to like $30 USD) or using a conformal coating on the circuit board/IC itself. I might take them apart at work to clean the old one better and Liquid Tape the IC pins/contacts in both to make sure this is less likely to happen again. (Or just grab some conformal coating off Amazon.) EDIT: UPDATE - So the problem came back. I finally had some down-time at work to inspect the light. (Better equipped at my job for this type of work compared to home.) So the corrosion I found was only part of the problem. It seems the corrosion ate enough of a contact on the main IC to make it loose while being able to intermittently bridge the connection or something. I tried re-soldering the contact, but had to file away the corrosion first. (Some flux didn't help much.) I did notice other solder points on the circuit board was treated with either a conformal coat (main contact points to the white LEDs) or protective film (USB connector, battery connections). Odd that Nitecore didn't apply it to the main controller IC. Anyway, the flashlight is seemingly susceptible to humidity and condensation build-up inside of it. Caution to those of you who tend to change environments with large temperature differences often. After my fix, I threw on a conformal coating for safe measure in the future. (I popped open my new one to put on a coat as well.) I'm still unsure what the residue under the battery was, though...

This is a great EDC flashlight. I carry one on my keychain, have a couple around the house, and have a couple always ready for travel. It's rechargeable and holds a charge for a long time. When in use it has a long life, especially on low. I find the three choices of brightness to be great because I often only need the dimmer light and it has many, many hours of capacity at that brightness. At the same time I sometimes want a very bright light and it can do that too though for less time. It also has a flashing white light, a solid red light or flashing red light. I don't use those often, but the flashing red light would be great in emergencies. It has a great clip on it that I can put on a shirt or a jacket pocket for hands-free use. I also often clip it onto the brim of my baseball cap. Then I can point it down at any one of a number of angles (it's adjustable) for hands-free light as I walk at night. It also has a sturdy metal lanyard to hang from a keychain or from a string in a tent or wherever. Hard to beat this guy!

I use this light on duty as a police officer and it is super convenient as a shoulder light to look at my notes. Great buy! Only downside is the whiney clip but I painted it black and it’s great.

The media could not be loaded. If you’re like me, you can never have too many lights on graves. This thumb is perfect. The separate buttons for red and white are great. The white is very bright and easily dims when needed. Buttons are tactile and easy to find at night. I found this light to be perfect mounted upside down. The clip is very strong and it holds in place fine. Right side up doesn’t allow the needed downward angles you need for patrol. Upside down allows for straight out light, then down to whatever angle you want. From effectively illuminating the car while issuing a cite, to all the way down to lighting up the ground while standing/walking. Add in the easy ability to dim the white light as needed and you have a winner for night patrol use. The white light on high lasts just under an hour. I dim it down to low when back at patrol veh. Working 12’s I charge the light every few days. Easy micro usb just plugs in while driving around if I want to top it up, but that’s rare. This light is a bargain for the quality and practical uses you get out of it. Just remember to mount it upside down with led’s facing out/down if wearing on molle. Also, I didn’t like the little chrome “holder” (used for a keychain I guess). I simply removed the 4 screws on the back, opened it up and the chrome loop comes right out without breaking anything. Update: I added a piece of 1 inch black shrink tube to the end to eliminate any led bleed. Still using the light each shift. Added video of how it works in a realistic environment to write a cite. It’s a winner.
