Now the bad part: the cap randomly come unscrewed on its own. Once it came apart in my pocket, which wasn't really a problem since it was able to recover all the pieces. The second time, it came apart at some point while retrieving my keys from my pocket in my gravel driveway. I noticed it was missing a few days later and had no idea where the parts were. Luckily, I was able to find the head and all the batteries in the driveway almost two weeks later, after noticing a reflection of light off one of the batteries. Everything had been rained on, there was grit all over the threads and there were gouges on the head (I'm pretty sure it had been ran over at least once). I quickly wiped the grit off the threads, screwed it back together and went on my way.
I believe the residual grit on the threads actually improved things, as the head has never fallen off again. It's been over three years and everything has stayed together with no issue. The head is still easy enough to turn with one hand, and the rain, grit and being run over seems to have had no effect on it.
Overall, it's a great light, but only if you can make sure it doesn't come apart.
**UPDATE - 12/8/2017**
Well it's been almost three years since I first wrote my review on this and it's still going strong. I believe I've changed the batteries once since buying it back in 2011. It's been on my key ring continuously for almost seven years now and it still works like a champ. I have no issues with the head coming loose or falling off anymore since the initial incident, so I anticipate having this on my keys for another several years.
Size and Shape--Advantage: Nano
Both the Nano and the Pico are .5 inches in diameter at the head, and 1.5 inches from nose to tail. However, they are shaped differently. The Pico is a true cylinder, with no real difference in the diameter of the head vs. the body. The Nano's head flares out, with its body diameter about 3/8". The slim body and flared head of the Nano gives something for the thumb to push against and makes it a bit easier to direct the beam where you want it to go.
Both lights are made from anodized aluminum with recessed bulbs. They are well constructed and appear ready to take some abuse. Both have knurled heads to give a better grip when twisting the lights on and off.
Both come in anodized aluminum in a variety of colors. (Incidentally, your color choice will have a major impact on the price of either light.) If you intend to snap either the Nano or Pico to a coat zipper, it will probably stay looking new for some time. If, however, you intend to attach it to your keys like I did, expect the anodizing to wear rather quickly with plenty of scratches. This is purely a cosmetic issue and doesn't matter to me, but if it does to you, be aware that neither of these lights has an extremely tough finish.
Battery Use--Advantage: Indeterminate
I haven't tested these for myself, but Streamlight claims the Nano will operate for 8 hours on one set of batteries, while UST claims 15. It's hard for me to believe that UST has perfected its technology to the point that it can nearly double the runtime of the Nano. Maybe Streamlight is referring to usable light, and UST is referring to the until-it-goes-out-completely number. If the Nano was brighter or the Pico dimmer, these numbers would make more sense, but as you are about to read, that's not the case.
Both the Nano and Pico list an output of 10 lumens. I can't tell any difference between the two in terms of brightness; both are extremely bright for their size. The throw of both lights is also equivalent. The Nano light is a bit more pure white, and the Pico is a bit more yellow. The shape of the Pico beam is a more uniform circle, and the Nano is a bit more oval-ish. Neither stands out for me as being substantially better. Let's say the uniformity of the Pico is cancelled out by the pure white beam of the Nano.
Some questions and other reviews have prompted me to add the following:
So how bright are the Nano and Pico lights, and what can and should they be used for? They are completely adequate, and sometimes too bright, for the following dark-environment activities:
1. Walking from your car to wherever you are going and back; from 0--20 feet, you'll easily identify anything you need to walk over or around.
2. Walking around your house without turning on the lights and waking up everyone else.
3. Finding something in a closet/purse/safe.
4. Reading (for me, too bright for this).
5. Signaling other hunters to organize drives or simply alert them to your presence.
As another point of reference, I can go into my basement (which has white-painted walls) at night with only this light, and identify everything, be it 1 or 40 feet away.
Dissatisfaction with the brightness of these lights is due to one of three things:
1. A defective light--I haven't experienced this.
2. Weak batteries--a situation that is easily remedied.
3. Unrealistic expectations--You shouldn't expect to use either of these lights for search and rescue operations, spotting deer, or spelunking. You won't use them to light paper on fire or to blind an onrushing attacker. There are many other larger, heavier, and more expensive lights on the market that can do all of these things--check out Surefire, Fenix, or high end offerings by Streamlight or one of the other dozen like minded manufacturers. The Pico and Nano are smaller than your pinkie and weigh less than half an ounce. Keep those facts in mind, and you will be VERY impressed at their light output.
Both lights function the same way. Point the light away from you, and twist the rear portion of the light clockwise (or the head counterclockwise) to turn the light on, and the opposite to turn it off. However, there's a difference here too. The lights are split differently. The Pico's twist point is 1/8" from the front. Sandwich that narrow head between your fingers, and you have the rear 1.25 inches to grab and twist. On the other hand, the Nano's twist point is .75 inches from the head, plenty of length to get between your thumb and pointer finger. However, that leaves your other fingers with only a half inch to grab. Because of this, you may find your rear fingers also gripping the front portion, fighting your front ones, and therefore making the twist more difficult than it needs to be. It is not a huge deal, and both designs function, but for me, the Pico's design is a bit better.
Battery Installation--Advantage: PICO
LR41 batteries are tiny. Two of them would make a standard pencil eraser. To insert batteries in the Nano, the best way I've found is to stack them on the counter, take the Nano apart, then slide the barrel of the Nano over top of the batteries, tilt it and put my finger over the opening, then screw it back together. At every stage of the process, those tiny batteries may try to scatter every which way. On the other hand, the Pico comes with a plastic housing that you slide the batteries into. Once they are in there, you can shake it and they won't come out. You then slide the entire holder into the light, screw it back together, and you're good to go. You will be able to manage either system, and with a minimum 8 hour runtime, you won't be changing batteries often, so battery installation is not a make or break factor. But the Pico's system is definitely easier.
Tendency Toward Self Destruction--Advantage: PICO
Many reviewers have complained that the Nano has a tendency to unscrew itself and come apart. Taking a tip from another reviewer, I used some thread seal tape on the threads, and I have never had the Nano come apart on its own. Truth be told, both lights have the potential of coming apart on their own, and both would benefit from the use of some thread seal tape. The difference is that if the Pico comes apart, it will be in three pieces, with the batteries all together. If the Nano comes apart, it will be in six, with the batteries scattered. Less tiny pieces to find=advantage Pico.
Snap Hook--Advantage: Draw
Both feature heavy duty snap hooks that allow easy attachment to keys and zippers. The surfaces of the Nano's hook are a bit flatter, while the Pico's are more rounded. If they are not exactly identical in size, they are so close as to make the difference negligible.
This is always subject to change, but as of early October 2014 Amazon listings, the Nano goes for about 8-9 dollars and the Pico for about 6-9 dollars, with your color choice determining the exact price.
There you have it. Unless I find in the future that the Pico does not share the Streamlight's durability, my keychain flashlight needs will be served by the Pico from now on. The price difference is reason enough, but the operation, promise of longer battery life, and ease of battery installation put it over the top. By no means is the Nano a bad product, and you shouldn't be upset if you find yourself the recipient of one in the future. But if you're the one buying, I'd go with the Pico.
The people who write these reviews raving about it obviously know nothing about flashlights or lumens. Or they get their product for free for raving about it. Well I am being brutally honest. Maybe I am spoiled after owning/using my Nitecore Tip for so long. I wanted something smaller and more compact.. boy what a difference. Now if you want a really good, really bright high quality light for your keychain, but a bit thick and bulky, I recommend the Nitecore Tip. It has 4 settings, and is pretty easy to use once you get adjusted to it. I do admit, a twist on/off is much more preferred, with 1 setting, but why bother if it's so weak?
I've been going on a bit of a binge with buying compact keychain lights as of late, it's a bit obsessive and redundant, but I know in the end, they will all get some sort of use, or they could make as good gifts for friends. I do hope to find a "not too expensive" high quality and strong light that is more in this form factor. I know it's out there, and that's why I am buying so many of them lately.
Top international reviews
I find these things are almost impossible to adjust to being off. When you're not using it, it will not stay completely off and will flicker unless you have it so loose that you risk losing the light head from the back portion where the clip is attached. This is completely unacceptable with any flashlight--but with one that I purchased with for potential tactical use--the last thing you want is your flashlight turning on or flickering when you don't want it to.
I also find that it drains batteries quicker than other similar flashlights.
I had intended this flashlight for my EDC keychain and my car keys and had planned to buy another 1 or 2 for my house keys to replace an ailing (and now hard to turn on) push-button micro-flashlight I had had for years. This was way back in 2013 when I was very new to Amazon and didn't realize that I could return it based on "did not work as described". But even if I had, I bought it on sale for 9 bucks and so probably would not have wasted the time.
So I couple of years later when I was in a dollar store, I saw a light that looked almost identical and decided to buy a few to test them out. These lights were literally $1.25. I still have many of those lights on my keychains and other places and they work great. The adjustment mechanism is tighter--so they stay off when they're off and on when they are turned on. And, they are actually lighter than the Streamlight Nano.
While not everybody experiences this problem or perhaps is aware of it, for $10 to $12, to me, it's definitely not worth it. I think that Streamlight--like many other companies (Black & Decker, KitchenAid and Stanley come to mind) that used to provide quality products from the time they started up until the late-80s--now simply seem to go with the cheapest overseas manufacturer available--causing the quality to continually decrease--while the prices of the products remain high.
Sorry for the delay in posting my review, but except for things I bought that completely did not work or were garbage I have not been writing reviews. However I have found that I've gained such valuable insights from many people's reviews that I would like to pay back and contribute in this way to hopefully help others get the best value for their hard-earned dollar, so over time, I plan to review most to all of my purchases.
The cons: the activation of the flashlight is done by twisting the light end of the flashlight toward the tail end. I found on several occasions that the light was actually on due to the two ends being pressed together hard enough in my pocket (unintentionally) to actually turn the light on. Also there were times when the two components of the flashlight actually completely unscrewed and separated in my pocket, making me have to fish out the batteries (which are extremely small and easy to lose if you aren't careful). There were also moments where I couldn't tell which way it needed to be screwed when I was in the dark and almost completely unscrewed it while I was just trying to turn it on.
If this flashlight was activated by a different mechanism such as a push button I think it would be much better. I would recommend this light if you are just planning on keeping it inside of some kind of case or bag (such as a first aid kit, or altoid survival tin).
However it is a good and convenient light to own, I just wanted to mention that the "screw together" activation is kind of annoying and may unscrew completely in your pocket.
Two problems - the finish seems to chip easily. I had mine for a couple of months, and the body of the nanolight is mostly silver now. The threads are also a little bit loose, meaning that it's easy enough to lose the two parts that comprise this flashlight. I stuck a bit of teflon tape into the threads, and now it's pretty much perfect.
I hardly used it, and totally forgot for last couple years, so the first sets of 3 LR41 batteries are gone.
I replace them, and it is perfectly working fine again.
Kinda too small if you have to light up for power outrage, but light is very strong (don't get blind!) and mostly used for stuff under fridges.
Good for hanging on your key holder.
Really bright for it's very compact size. Doesn't take up much additional space in your pocket and it's been quite handy already a few times at night.
A tad awkward to turn on one handed, but doable in a pinch.
While I liked the Nanolight, as a warning I've heard that some people have had issues with this flashlight unscrewing itself in their pocket. Hasn't happened to me yet and it's been a part of my daily carry for months, but if it does a little bit of teflon tape on the threads should fix that(and make the flashlight more water resistant at the same time!)
There is a consequence to getting so much light out of such a small size using watch batteries... If you make use of it frequently(like I do), then be warned that it will burn through batteries, but amazon sells them in bulk... That many will last you a good long time, even if you really really love your Nanolight.
If you want a little keychain flashlight I'd definitely suggest giving this a try.
Bitte die drei Sterne nicht falsch verstehen, das Nanolight ist sicher eine gute Mini-LED, die Batterie hat auch noch nicht "schlapp" gemacht - für den Preis habe ich mir mehr versprochen. Trotz allem - wenn der Preis für Sie stimmt, zuschlagen!
In spite of that, it's brighter than the 6 LED light it's replacing.
I'm not entirely convinced that a twist-switch light won't turn itself on in my pocket. I think it could have been a tad stiffer to turn. But we'll give it a go.
