Handiest EDC Flashlight
This is the most convenient EDC light I have ever had. I really like the size. The battery life is great. I read some reviews that said the on/off button was hard to press. I find that is a benefit for me becauseI do not have to worry about the light getting accidently turned on in my pocket. Another nice feature is that this light is small and light it is easy to hold in my mouth (not recommended, but it works for me) and it works great on a cap bill or hat brim. Great choice for EDC. I love it.
ProsSmall and light. Long battery life.
ConsNone

EDC light
Have carried one of these for the last few years, small enough to fit in watch pocket of jeans, really good power for the size, cheap enough to replace w/someone "borrows" it. Two-way clip is good for hat, cuff, clipboard. I buy several at once, great for Secret Santa, stocking stuffers, last-minute office gifts. Also will survive multiple trips through the washer/dryer.
ProsPowerful for size, small enough to be available at all times. Spare endcap switch cover a big plus. Two-way clip very versatile.
ConsEndcap switch initially needs coaxing, OK after first few uses.

One of my favorite EDC lights.
Love this little guy. Gives me enough light to do tasks at night and the reverse pocket clips is a life saver when I need both hands free, just clips onto my hat and I have a headlamp! It's small and light enough to carry on my pocket and not bother me. I do wish the pocket clip were sturdier. I have lost it a few times because the pocket clip slid off my pocket and in between chairs. The tail cap is a bit hard to press but not really an issue for me, but may be for others.
ProsLightweight, Small, Bright, Reverse pocket clip is useful when you need both hands, Momentary on.
ConsTail cap might be hard to press for others, Pocket clip could be sturdier so it won't slip out of your pocket.

Best EDC flashlight I have ever owned!
This is hands down the best every day carry flashlight I have ever owned. I was heartbroken when I lost my first one and immediately ordered two more! It's small, bright and the pocket clip is in the right place to make it easily accessible. it gets unbelievable battery life from one AAA! Not only have I recommended this to a friend, I have given them as gifts!
ProsSmall size, very bright, great battery life.

Good and bad
For me, any small light must have a good pocket clip so I can hook it on the inside of my pants pocket. Can't stand to have it loose in the pocket. This light has the best clip of all the lights that I have. The light beam its self is OK, no better or worse than my other single aaa lights. The rear activation button is a annoying problem. It is so hard to turn on or off that it almost takes one hand to hold the light and the other to push the button. The product does seem to be high in quality.
ProsGreat pocket clip. High quality.
ConsVery hard to use on/off button.

Best mini flashlight
This is one of the most useful flashlights I have ever used. It is small enough to carry everywhere you go. The light is very bright and runs a long time on one AAA battery. This is my go to flashlight for most applications.
ProsSmall, batteries last a long time, very bright light.

Five-year review: excellent!
This is a splendid little light that I have had for at least five years, several drops, and even a few trips through the washing machine by mistake. Because of its compact size, it has been clipped to the pocket of my jeans every day, and has become the sort of handy tool that makes me wonder how I ever got along without it. It fits in my hand perfectly, so that I can use my pinky to cover the end and dim the light if all I need is a slight amount. One AAA battery lasts at least six months, and this unit gives out as much as a big ol' Maglite used to provide back in the day.
ProsCompact enough that you can always have it clipped to your pocket and ready to use, and use your pinky as a dimmer. Pretty bright for its size, and low battery consumption.
ConsNone!

GREAT LIGHT. SMALL AND BRIGHT AND LASTS LONG TIME ON BATTERY
I AM A TELEPHONE MAN WHO INSTALLS WIRING IN CEILINGS OF HOSPITALS & FACTORIES. I PUT THIS LIGHT IN MY TEETH & CAN AIM IT ANYWHERE THIS WAY. I HAVE DROPPED IT MANY MANY TIMES & IT REMAINS WORKING. I USE THE AAA BATTERY AND THE LIFE OF THE BATTERY IS TERRIFIC. IT HAS AWESOME LIGHT OUTPUT. I HIGHLY RECOMMEND IT TO EVERYONE.

Terrific EDC light!
I have several MicroStreams! I think they're one of the best values out there in small EDC lights. They have a very good clean spot with an excellent balance between spot and spill. The color of them is overall very good (although my newest one is biased a bit more towards cool/blue than my other ones). The switch is excellent and very durable; my oldest one has been used hard for several years and still works fine. The finish is holding up very well, too. The two-say clip is excellent and versatile. For carry you would normally use it lens down but the S-shaped clip can be reversed to clip to the brim of a hat or ball cap. The size is perfect. It's one of the smaller AAA lights I've used. There are brighter lights out there but the MicroStream offers a good balance between output and battery life. I run lithiums in mine and usually get a year of EDC use between battery changes. I'd estimate a Lithium cell to provide about three hours of steady light, depending on temp, etc. Lastly I appreciate that Streamlight throws in a lanyard loop and a spare rubber boot for the clicky switch. That's a nice bonus that should keep the light going for several years. This is a great light and a great value. No point in carrying junk when you can have something like this for well under twenty bucks!
Pros* Good output * Water proof * Excellent shock resistance * Superb reflector with very clean beam * Highly functional pocket clip * Very compact * Nice finish * Includes extra rubber boot for clicky
Cons* Could be brighter I suppose * Clip isn't removable

Great Pocket Light
I've owned (and lost) a number of these over the years - good thing the price is so reasonable.. Nothing fancy, won't blind anyone, but plenty of light when you need it the most - and you'll have it because it is small enough to carry everywhere.

Microstream
Very nice little light! Someone once said "the light that will do you the most good is the one you have with you." This light is very easy to have with you when you need it. I really like the two way clip. You can have it in your pocket or on the bill of your cap for hands free use. Good job Streamlight!
ProsSmall, easy to carry, light weight, two way clip.

Carry everywhere
I have this in my pocket every day for a couple of years. I have not had trouble with accidental activation carrying this way. Having RP low vision problems, I am always in need of a bright light source. I have used it for dropped items to working on machines to reading menus in dark restaurants. I use rechargeable batteries and they have good life for just one AAA..
ProsHolds up over time and usage.

Did you ever own something that just 'worked'?
That's the Microstream. I have owned Microstreams since they first came out. Like all Streamlight lights, it is well built and well designed. It is amazing how much light it can put out for a single AAA flashlight. The relatively deep reflector plays a part there. The beam pattern is nice, with few to no artifacts.I have EDCed this light for almost ten years now (not the same one, they keep running away from home!), and have no plans to switch to a different one.
ProsWell Built Inexpensive, especially for the quality Two-way pocket clip Bright Good run time, especially with lithium primaries
ConsOn/off switch is a little stiff. I liked the version 1 switch better, but I guess people had an issue with it being too easy to turn on inadvertently..

Amazing throw for such a tiny light
I've had one of these for some time. In terms of lumens, it's no brighter than one might expect, but the reflector design is exceptional, resulting in a nice concentrated beam that will reach out across a room in the dark to check window locks, ceilings, or whatever you need to see. The beam is cleanly transitioned to a bright center, with no dark shadows or irregularities. Like all small, low-powered lights, it excels in totally DARK areas, as any ambient light will compete with it and cause your eyes to adjust, making the flashlight less effective. It will make it seem dimmer to your eyes. A battery lasts a fairly long time considering how much you get in terms of throw distance. It's also a well-built, tough little light. The rubber switch cover is still intact on mine despite between 2 and 3 years of use. It is very small, so it can be carried in a pocket with no hassle at all. The pocket clip works well and mine has held up just fine. Highly recommended. The best AAA light I've used.
ProsSmall size Excellent throw Clean beam transition to a bright spot - no shadows or irregularities Good pocket clip Gets a lot of time out of one AAA battery
ConsDoes not come with a sheath Brightness limitations inherent with size constraints

Streamlight Microstream LED 66318
I work graveyard shift at a hospital and need to check patient's ID bands. The Microstream is perfect. Small enough to carry in pocket and provides more than enough light. Very well made. Tailcap switch easy to push for momentary light, takes a bit more effort to click for constant light. Replaced my Streamlight Stylus Pro which I like very much but my sweetie said it was tearing my pocket. Win, Win: I get to buy another flashlight and it will hopefully keep her happy. Have not had it long enough to comment on battery life, switch longevity, etc. but its a Streamlight. Good enough for me.

An amazing little light
I have ordered several of these lights over the last month because anyone that sees it wants it and for the price on battery junction you just can\'t beat it. It\'s a perfect light for carry in your pant pocket or shirt pocket. My wife also wanted one for her purse. Overall i rate it a 5. I have not found a deficiency in it if keep in mind it\'s size.

No Brainer
This is a perfect every day carry - simple and tough, its rare to find a small light with a rear clicker switch....its only 20 lumens, but that is plenty for most uses....if you have only one light, you could do worse than this little light that fits in your pocket, very light....match it with some rechargable AAAs and you are in business, never ran mine with Lithiums, maybe even brighter?

Tiny, Tough, Bright!
Incredible light for its size and weight. The light runs on a single AAA battery but is brighter than my Maglite that uses two AA batteries! Just like the reviewer before me, I accidentally put the light through a wash and dryer cycle... and it still works! I love this light.
