    • Excellent EDC flashlight
This flashlight was a great buy. It is a very good EDC flashlight. It’s small enough to clip on your pocket and keep it there all day long without it being obtrusive. It’s bright with good battery life. I use it quite a bit and only charge it once a week. I never realized how often a flashlight comes in handy until I started carrying this one every day. It is well worth the price. I like that it has two levels of brightness. For close up work, the high level can be blinding but the lower level is very comfortable when up close. ... show more

    • Serious Use, Compact Size
Great light and I can’t believe how Streamlight has progressed. I’ve carried a ProTac 2x 500 lumen for ages. Amazing that this is the same output and similar runtime in a comparatively tiny form factor. It’s quick and easy to use, super bright, and is a perfect balance of design and output for serious use while being small enough to be convenient every day. Rechargeability is also a big plus. ... show more

    • Not the usual Streamlight quality
I bought this Macrostream USB to replace one just like it that got lost. The original one I had was a very good light for over two years until it was lost. The new light doesn’t function correctly. The light should turn on in the bright setting and then can be switched to the dim setting. This light works the opposite. The battery life is also really short even compared the light that was two years old. I did contact Streamlight Customer Service and told they do not guarantee lights that are sold by third parties on Amazon. ... show more

    • Lasted 4 months with heavy use and abuse
Purchased the macrostream 4 months ago for 60USD total from Amazon with free shipping. Used the flashlight everyday at work until it stopped working today. Flashlight was one of the best edc flashlights I had used in a while. I found the momentary on and high low settings very easy and quick to use. The clip was very strong and has great pocket retention, sometimes after work I would mow 2 acres of bumpy hilly terrain and it would be there every time. The double sided clip allowed me to easily draw from pocket and clip it onto my hat for hands free use or sometimes even nearby wires, cables, sheet metal. The high mode was blinding for self defense and the low mode was perfect for inspection. The battery life was better than most and would last all day most of the time. Having one extra battery on hand would eliminate any battery life complaints, I did not carry one though. I dropped this flashlight A LOT no exaggeration, several times a week at well over the 1 meter shock test. Over the past week it started to flicker and I would have to tap it to get it to stay on. Eventually it stopped working. I took it apart and found that the led was shot. Overall I was very impressed with this flashlight and if taken care of I’m sure it will last the 30,000 hours /3.4yrs the led is projected to last. I will be purchasing a new one from streamlight on Amazon today and will try not to drop it. ... show more

    • Best Flashlight For EDC
I do not usually write reviews, but this one needed a 5 star. I bought this before a trip to Mexico just in case and I ended up using it in a Cenote (natural sinkhole) and I was skeptical if it would be able to handle being underwater for 1 hour. However, to my surprise it performed perfectly and lit up the cave which helped us explore our surroundings. My tour guide was so impressed that he wanted to know what kind of flashlight it was and how it was stronger than three of his flashlights combined. The build quality is excellent and feels really good in the hand also. The button also feels really nice to click and tap. ... show more

    • Great micro flashlight
I own several flashlights, and this one is close to if not my favorite. I use it for work (septic systems) and it will light up a tank or down a deep cleanout really well! The hat clip is also really useful. The battery life leaves some to be desired, but other than that it is great! It will probably run for 30min+ on high. ... show more

    • IT'S NOT USB C!!!! And works fine. Explanation in the review.
Update: Still feel the same way about a micro USB but if you think the thing is broken when you get it (I did) it's because you haven't figure it out. Tap the light (don't push) and it comes on bright. While holding it at that brightness, tap again and It will go to low power. When you have one or the other showing, press firmly and that's the light you will get. I had no clue what I was doing and came within a breath of sending it back. I apologize to the store and the manufacturer for being clueless. Updating to 5 stars. The bright is very bright the low power works well in low light. This day and age, I "Assumed" that it would be the, now, standard USB C. It actually micro usb! Go figure. I am half way tempted to return the thing because of this. I now have to dig into my old junk drawer to find a micro usb. Oh it is one good flash light. Just this old technology, for something this expensive, disappoints. The fact that it states it is a micro usb is besides the point. That info was buried. And I could have asked does it have X-Ray capabilities, but I KNEW IT DIDN'T. This day and age one should be able to just know it is now the current standard. Update: Dropped from 4 to 2 stars. When it started it had a low power and high. Now it only has high and that is sometimes. If the barrel gets turned, it will light at a press but won't stay on. If you turn the barrel, it will now stay on but only high power. The "barrel" I refer to is the "sleeve" that you push up to reveal the micro usb. What that has to do with it, I have no clue. Double press only turns high power on quickly. Certainly not worthy of the EDC tag. ... show more
