Great, slim, bright, tough
August 23, 2016
Like many others here I have a lot of flashlights. This light is a good combination of flood and throw. It has a little more flood than throw and that makes it better for my use. I like the switch design and it becomes a real bad ass when you add the tactical bezel and window breaker on the rear. Of all my lights this gets a lot of attention from friends. Just don't try to put it in your pocket if you upgrade the bezel and add the spike
ProsBright with plenty of flood and enough throw when needed on high Love the tactical bezel and window breaker upgrade
ConsHad a hard time getting the original bezel off. would be nice if it had USB or a base to recharge it.

Simply Excellent
July 8, 2016
Bought this baby after doing some online research. It's the first tactical flashlight I've owned, so I can't make any comparisons, but I can't think of anything I'd change. The flat cap lets you stand the thing upright and ensures that the batteries are snug, the switch is just where you want it and is easy to use, it fits perfectly in your hand or your pocket, and the beam has to be seen to be believed. It's a practical device but it's also one of the coolest toys I own.
ProsYou name it.
ConsNone so far.

Really comfortable to hold and use!
June 12, 2016
This is the absolute winner for ease to hold and use. The two side by side 18650 battery configuration fits easily in your hand, keeps the side switches oriented correctly, stops rolling on a table, and even fits in the back pocket of your pants. This is my first flashlight in this configuration, but it is instantly a favorite. The range from moonlight level to over 2000 lumens is impressive. The beam is a very broad spotlight, a nice even wide beam. This flashlight is great for everything in between an EDC and a high powered search light for long distance. Get it, you'll love it.
ProsComfortable in hand, light intensity range, wide beam

My new go to light
March 23, 2018
I'm loving this light, and as a true flashlight lover that's saying something. For me to choose this light as my go to, primary, if I had to pick only one light, light it had better be great.

For starters, it's relatively small for what it is, well shaped, easy to hold, and easy to use. It came with a holster which I use for travel, but it's small enough to fit in a pocket if needed.

It's tough. It's cool looking. It's got great range of light (from low to high), is super bright for its size, and the beam pattern is great for an overall light. More on the floody side for sure, but a nice color of light and bright enough to still let you see far away.

My old primary light, you know the one you take on a weekend car trip or camping or something similar and can only bring one main light, was the Nitecore EC20 generally or maybe my Olight S302, or maybe my Fenix PD35. But this EC4S light easily replaces all those. It's not much bigger, has more useful modes, twice the battery power, and outshines all those by 100% when I want it to.

As for durability, I've had mine for over a year and used it often. I have no problems with the cap, in fact I like the way it screws on. Batteries don't seem to need a recharge when the light sits idle for a while, and the lens seems well protected by the body.

Overall, great light. When friends ask which light is my favorite, this is the one I choose.
Pros- Really bright for size - relatively small and ergnomic - seems tough, has lasted so far with lots of use and no problems at all - super easy to use - good range of modes - great general purpose light - the one I choose when I can only have one light
Cons- Tendency to show off the brightness and drain batteries - slightly too big for EDC in a pocket - red anodized tailcap will turn pink if I leave it in the sun probably - would be cool if it had rubber grip marks
