MecArmy X2S Stainless Steel LED Flashlight, Mini EDC Rechargeable Keychain Flashlight with Micro USB Charging, 10180 Battery 130 Lumens Outdoor Waterproof EDC Keychain Light (DLC Black)

Pro: Light, well made, seals look waterproof, extremely bright for its size, screws on and off so can't go on by accident, there when you need it, keep on key chain.Con: None really, a bit pricey but worth it. Can't say how long battery lasts but charge with USB.

I like the light. The size is nice and the light is bright enough. However, the cap is almost impossible to grip and twist to turn on the light! Is it supposed to be so tight? It’s difficult to grip because there isn’t really any checkering. The little grooves cut into the flashlight aren’t really useful for providing a grip. Plus, the rubber washer make makes the cap fit super tight. It takes serious effort to grip the cap and body and then to twist. I don’t like that. If I leave the cap close to the “on” position, I can just depress the cap towards the body of the flashlight to turn it on. Not sure that is recommended by the manufacturer.A week later. It loosened up and is now much easier to use. Changed my rating to 5 stars.

I purchased the flashlight in November, charged it and took it on a trip. Had rented a house very close to a cliff and wanted to have a flashlight handy each time when getting home in the evening. Used it a lot that time. Last night, Feb 25, 3 months after the first and only charge, it was still charged when I had to do a small job on my car. Love it.

This is a good keychain light. It's not without flaws, but still the best I've tried.Pros:- Very small package. Perfect for keychains.- Emits and impressive amount of light for it's size.- Waterproof design.- Two brightness modes (and no gimmicky modes like strobe and SOS to to cycle through all the time).- Durable stainless body. No need to worry about smashing it, scratching off the paint or anodizing, or rust or other corrosion.- USB port is concealed in a waterproof area under the head, yet it can be charged without completely removing the head from the flashlight. This prevents accidentally losing parts while charging. I've had other lights where I had to completely remove the head and risk accidentally loosing it, and lights where the USB port is exposed to moisture and debris, sometimes with a rubber "shoe" that eventually breaks off.- Twist-on-off completely cuts off power when off. The majority of LED flashlights have a small power drain when they're "off" because they use momentary switches that require a small amount of power to internal integrated circuit to detect switch presses.Cons:- Charges via Micro USB. Micro USB is the worst for durability and ease of use. To make it worse, the charging port is also recessed into the body of the light about 1mm and you really need to use a micro-USB cable with a slightly longer connector to make a good connection. I've got several micro USB cables and only a couple worked well. The rest worked, but lost connection with the slightest movement since the contacts are just barely long enough.- Twist-on-off switches are somewhat easy to accidentally turn on in your pocket and this usually gets worse over time. Replacing the O-Ring will help and this light comes with a spare, so that's a bonus, but it won't last forever. This light is better than most since you can turn the head farther to make it less likely to accidentally turn on, yet not worry about the head falling completely off.- Twist on-off switches risk compromising the water-proof seal every time you use the light, and the risk gets worse as the O-rings wear out.- Expensive and uncommon 3.7V 10180 lithium battery. A search on Amazon right now yields just a handful of sellers with the lowest price of $17 for 2. They're available from Chinese wholesalers for a lot less, but shipping takes weeks and you're always at risk of buying items that didn't pass quality control.

I bought a MecArmy SS Keychain light about two years ago and unfortunately my Keys were lost at work. I was impressed with the light after owning several other keychain lights so I immediately order a replacement.What I likeRechargeableSmall sizeBright – Low level is good for 90% of use.QualityDesignRuntimePrice

Showed up non-functioning. Plugged it in immediately, charging indicator turned on but would NOT turn on no matter what i did. I notified the seller who insisted i send it back rather than just send me another one. Why would they want a broken light back? SO THEY CAN SEND IT OUT AGAIN?

I bought this model in 2017, when it was called the worlds smallest flashlight. Still using it. I had to replace the battery though. And the O ring. The O ring is integral to the function. Without it, water can get in and you could accidentally turn the light on because no resistance.The O ring will break a part due to age and use. I would try adding a silicon safe oil to make it last longer. Otherwise, its a great flashlight. You won't even notice the weight on your keys. Strong build aside from the O ring....

Very well made flashlight. Tiny, but very powerful. Add rechargeable to the equation and a perfect light for my key chain!

So ist die Lampe schon schön anzusehen . Aber was mich stört dass sie im ausgeschalteten Zustand doch etwas lapprig ist da man den Lampenkopf locker drehen muss um sie auszuschalten bei leichtem Druck auf das Lampengehäuse selbst geht sie dann an kurz . Besser wäre ein Schalter . Das Aufladen erfolgt am losedrehen des lampenkopfes dadurch kommt die USB Anschlussbuchse zum Vorschein der Lampenkopf bleibt aber am Rest hängen erst beim weiter aufschrauben kann man ihn dann entfernen .braucht man aber nicht . Toll wäre ein Schalter und ja wasserdicht sollte sie sein. Gegen untertauchen geschützt .So richtig knallhell ist sie nicht verarbeitet ist sie gut . Aber das drehen nervt ist sie jetzt aus . Oder geht's sie wieder an .Auf jeden Fall ausbaufähig 1cm länger mit Schalter wäre immer noch im Rahmen und wasserdichten USB keine Silikonkappe wäre nett gewesen . Hab sie am Schlüsselbund nun hängen da für Verwendungszweck ungeeignt
