Review: 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.
Review: Worked for 6 years, and is small enough to fit a key chain - Amazing small flashlight that works in a key chain and fits nicely in your pocket. Is bright enough for any needs I've had in the past 6 years in all temperatures. The two lighting intensity options have also come in handy, and the brighter intensity being the primary one has been essential; only sometimes wanting to use the dimmer option by double tapping the activation button. By feeding a zip tie around the end of the clip area loop, you can then use that tight loop for a key chain and the flashlight will stay in place while still allowing for articulation in the key chain. The seal to the charge port has worked fine, even surviving half an hour in the snow after I accidentally dropped the flashlight there and later went looking for it. I haven't felt the need for another flashlight ever since I got this, and having it always with me with my key chain has been a positive in some unexpected scenarios.

### ⭐⭐⭐⭐⭐ Badass Candle.
*by R***E on February 6, 2026*

This is one of the most useful tools in my arsenal. I use it for EDC, and damn does it come in handy! I use it everyday. I actually purchased 4 of them so far because they are that good. Very bright, can be clipped to your hat for use as a headlamp, has two settings, lasts for hours, and it's rechargeable. What's not to love? I have 3 of the 4 flashlights left ('cause an ex-girlfriend stole one) and I purchased all in Coyote. Amazing little light! Be sure to charge it up before use/upon receipt so the battery reaches its maximum power, potential, and longevity. The oldest one I have still burns for 6+ hours and I bought it in 2021.
