Best small flashlight I’ve ever owned.
Great low-profile flashlight. Pocket real estate is at a premium for me, so the size of these is perfect. I often have to use my mouth to hold flashlights at work so I can use both hands, and this has been the most comfortable flashlight my lips have clasped. I use it everyday and I use it A LOT. I have to keep an extra one of these in my backpack because sometimes the battery runs out before my workday is over, but usually it lasts me all day. Love that it’s rechargeable. I used it for over a year before I noticed it started to die quicker. I just replaced the old battery with a new stream light rechargeable battery, and it was like new again. Still WAY cheaper than a flashlight that just uses standard AA/AAA or CR123 batteries. I work on cars, so I’m never using it for anything more than 6 feet away, but for my purposes, this flashlight has been the gold-standard I measure all small handheld flashlights against. The amount of brightness you get for the size of the flashlight is top tier. The pocket clip snapped and broke on my first one after a couple years, but like I said, I use this all day everyday. I’d still say the durability is great for the price. I had to remove the pocket clip on my new one and squeeze it with some pliers to make it clamp down tighter because it kept falling off my pocket. Since then I haven’t had any issues. Love this little flashlight. I went through about 5 or 6 small flashlights before I found this one. This one is better in every way. As long as the price doesn’t go any higher it’s a 10/10 will buy again when I inevitably lose mine.

Wow
This is an amazing light. The one thing that I love about the Coyote Color Streamlight is that it does the high which is 250 lumens then when you double tap it then it goes to the low setting I use this light on high for quick inspections and then a brighter light for other work. The charge is amazing. It is a very compact size. And for the money and lifetime warranty you can’t beat it. It doesn’t get hot like a lot of lights do and you can’t beat the functionality's best value for the money.

High quality Admin / Task Light
Great mini task light. Easy to use. One button push for low. Two for high. Click for constant on. Light output is good for its size. Enough to be usable. Good Hotspot / focus for a mini light. Rechargeable batteries is a huge plus. Power / battery life is good. Small form factor. Easy to carry in a bag or pocket. Takes up little space.

Best pocket flashlight I’ve ever had
I’ve beat the piss out of this over the past year and it still functions flawlessly. It’s bright, has two modes for light intensity, is incredibly small in my pocket but feels good in my hand, and doesn’t need charged often. I’ve worn the paint off of parts of it from heavy use and it’s never failed. My only wish is it charged with usb C but it’s such a small gripe that I feel petty saying it.

Good pocket light
Pros: Compact size (the length about the size of my index finger from tip to knuckle, I use XL gloves) Lightweight (Stays in shirt pocket and doesn't fall out) Good Brightness Metal case, so should be fine from 5ft drop onto cement (haven't tested yet tho) Rechargeable, if that model is purchased (about 2-3hr if fully charged) Cons: "focusing" lens/adjustment is virtually pointless, as in barely makes a difference (tip slides out to "focus" light beam ) The On/Off button modes This is my biggest gripe and The reason I gave this light a 4star instead of 5stars I believe the button has 2 modes of use 1: press lightly and hold button down for quick inspections or uses (manually keeping light powered on 2: click light on/off, for extended periods of use For the 1st mode, Light works great, highly recommend if you plan to use it like that, BUT the 2nd mode is where I have my issue. The button require alot more effort to click on/off than it should. I started thinking I might be getting arthritis (I am a mechanic so possible) because sometimes I could not click it on/off without pressing down fairly hard. I assume it's an issue with how "small" the button is (the rubber isn't as squishy, so more resistance) but I have had times where I'm having to actually "think" about how I'm pressing the button, because I'm unable to click it on/off, I've never had similar issues with other lights before, except for when the button was broken. Edit: I added a small piece of paper under the button (you can unscrew the button) and now I can click it on and off effortlessly. Also added pictures showing the "focusing" function.

Awesome EDC flashlight
Awesome rechargeable edc flashlight. I have the non rechargeable version I bought 12 years ago. Still works great, it's just my kid decided it's hers now since all of the other flashlights don't work anymore. These stream light flashlights last forever. I still have my uv stylus that's about 20 years old. This newer upgraded micro stream is fantastic. It's significantly brighter and has two power settings, and it's rechargeable!!! I also like the coyote brown color. I may also give the Macro stream a try as well for camping

The flashlight is great but has a flaw that it gets hot fairly quickly on both high and low setting

Tamaño y peso ideal a una mano para llevar a todos lados, mil usos, utiliza solo una pila triple A incluida, viene con una correa, me gusta el boton de encendido momentaneo o permanente a diferencia de otros modelos o de otras marcas. Resistente, durable, calidad, 45 lumens. Previa experiencia con la marca, he usado otros modelos, prefiero de pila alcalina a recargable.

Small dog walking torch, the pen clip is great as is the battery life. Love the red LED indicator when it’s getting close to be recharged. Loads of light with nice wide areas shown.

Es la mejor lámpara que he visto de ese tamaño, no ilumina tanto pero para su tamaño da muy buena luz, es recargable llevo más de un mes de uso regular, obvio no continuo, y no la he vuelto a cargar.
