Perfect for automotive
I started school recently in the automotive program, I was looking for a small flashlight to keep in my shirt pocket but also bright enough to see in small dark places. This does everything I need it to do. The light output isn’t a groundbreaking brightness but it makes it plenty light enough to see. It has a small adjustment for a narrow beam or wide, again, just fine for what it needs to do. The battery will not last forever so just make sure to keep it charged beforehand. I’d recommend this to anyone considering the build quality and price.

Lightweight, slim, great pen light
This is a great pen light. It's 400 lms which is a pretty bright stream of light. My husband is a mechanic so he always needs to see into small spaces. He really finds a pen light useful as he can hold it in his mouth. (Haha) he tried headlamps, but they're hard to get just right. This light is light weight and slim. (Which again makes it easy to hold) It's rechargeable. Which for us is a bonus. We spent a lot of money on batteries over the years. This light feels well made. It is on or off, or you can quick press to make it strobe. Has a clip so you can easily put it in a shirt pocket or any other pocket, for easy access. My only complaint is I thought the red slider was to make it from a point to a broad light, but there's no options like that. The good of the red slider is its to cover the charging port so if you drop it in the dirt, you can still charge it, without ruining the light or charger. All in all it's a great light weight slim light for a great price.

Still no USB-C??
Best pen type flashlight on the market. Only 2 problems that I had, 1 I dropped it a few times and it’s claims of durability aren’t as good as they say, they were never more than from a couple of feet. The easiest fix though is the charging port. It’s 2026 people, USB-c is pretty standard even on cheap toys from China. I think energizer can figure it out. Otherwise this is a great buy, super bright and heavy in a way that makes you feel like it’ll last for a long time(although mileage definitely may vary). Would recommend or buy this for friends and family for sure.

Worked but heats up and port falls out
Edit: plug just fell out Purchased just several months ago, things were going good only complaint for a while is the flashlight got really hot while in use. It's still really hot while in use, sadly now the plug in port to charge has come out, it's still attached to the inside but it's dangling out of it's spot. Definitely NOT very safe to continue to use unfortunately. It is a very bright light still though. Guess I'll be searching for a new flashlight now.

I like it.
I bought this light to replace my NEBO pocket light. I like Energizer products for their longevity. This light is super bright, adjustable, dependable, and light weight in my shirt pocket. The only thing I dislike is when the rechargeable battery needs recharging the light just shuts off, no warning, now dimming, just shuts down. That can be irritating when you're in a well house at night trying to get the water back flowing and it decides it's time to go to sleep. But other than that experience it's an awesome light, in my opinion not as good as my NEBO but it's not $60 either, only $15. I've been using it several months now with no issue, well except the well house deal, and I hope to get at least a couple of years service from it, if so, I'll replace it with another Energizer pocket light. I would definitely recommend it.
