Review Image by RRR
Great personal-carry flashlight! I clip this to my back pocket and forget it's there until I need it. I've been carrying this flashlight for four months and have charged it three times. Hasn't run out of power even after frequent use. The regular brightness is good for up close work and the extra bright setting will light up a large area around you. It weighs so little that you can clip it to a hat brim and use it as a headlamp. Seems sturdy; I've dropped it a few times and it still functions without any visible damage to the exterior. Costs a little more than some of the other personal-carry flashlights on Amazon, but you get what you pay for. Worth the $ This light is so handy I'm planning on ordering more as stocking stuffers for family and friends. I appreciate that this unit is rechargeable. Saves a lot of money on batteries and it holds its charge really well. Addendum: I have now owned the same flashlight for going on three years and it still works amazing! I've dropped it several times and even forgot to unclip it from my jeans before I ran them through the washer and the dryer. Not only did it survive the washer and the dryer, it was still firmly clipped to my pants! Still holds a charge for weeks. Outstanding flashlight! I will absolutely buy another if I ever loose this one. I did buy one for each of my family members and they all love them. I even have a few friends that have purchased the same flashlight on my recommendation. None have been disappointed. So nice to find a useful product that lives up to expectations. Thanks! ... show more

    • Really bright, really compact, and well built. Just wish it was USB-C instead of Micro USB
Style: Clear Retail Packaging Size: 3.87" L × 0.61" W × 0.61" H Color: Black
Great quality streamlight. Just wish it was USB-C. Micro USB is okay too and gets the job done. Cable is included. Very bright and good beam.

    • Flashlight
Style: Clear Retail Packaging Size: 3.87" L × 0.61" W × 0.61" H Color: Black
The flashlight is well made and light. It fits well in a pocket. My only concern is it’s much smaller than expected and the tail switch is hard to lock on. I hope after more use the switch be easier to lock on. Otherwise the flashlight is bright and provides two light intensity modes. Charging process is quick and easy and the battery seems to last a long time. ... show more

    • Best EDC light I've ever had
Style: Clear Retail Packaging Size: 3.87" L × 0.61" W × 0.61" H Color: Black
I've had pocket flashlights in the past but they were long and required AAA batteries. This light is half the size but just as bright, if not brighter. A lot of the cheaper brands claim to put out far more lumens than they actually do, but Streamlight's 250-lumen rating is definitely accurate. You get what you pay for. It's lightweight and compact but capable of illuminating a room. I generally run it on high, but in some applications, low is more than enough. The pocket clip keeps it securely in place, and the front shrowd pulls forward to reveal the micro-USB charging port and indicator light, protecting it from dust. It charges up quickly and the battery life is impressive. It does not zoom or strobe, but those were features that I rarely had a need for on previous lights. The center of the beam is tight enough to highlight objects but still illuminates the whole area. I do wish it was a type-c port, but it's not a huge problem given how often I have to charge it. I wish I had just coughed up the extra $10-15 in the past and gotten this. ... show more

    • Great light in a small package
Style: Clear Retail Packaging Size: 3.87" L × 0.61" W × 0.61" H Color: Black
These are great little flashlights. They are surprisingly bright for as little as they are. They are small enough that they can be carried very easily. This is my second one that I ordered so I could have a spare.
