Compact, Powerful, and Convenient!
I’m thoroughly impressed with the Streamlight Stylus Pro USB Penlight! This little light is incredibly powerful for its size. The 350 lumens provide excellent brightness, making it perfect for close-up tasks or even for lighting up a dark room. I use it daily for work, and it’s come in handy countless times. The rechargeable feature is a huge plus. No more constantly buying batteries – just plug it in with the included USB cord, and you’re good to go. The battery life is fantastic, lasting several hours on a single charge. Plus, the nylon holster it comes with is convenient for carrying it around, and it fits comfortably in my pocket or on my belt. The design is sleek and durable, and I love that it’s water-resistant. Whether you're out in the rain or using it in tougher conditions, this penlight holds up really well. Overall, it’s a perfect tool for anyone who needs a reliable, portable light.

Great Light BUT why Micro USB-C
I love this light, and use it all the time. Its is very bright for its size and it is lightweight. My only complaint is why is the micro USB still being used to charge these lights. The micro USB is so prone to breaking and starting to become outdated. I look forward to the light being made with a USB-C charging port.

Durable Flashlight
This is an excellent rechargeable penflashlight. This is the second purchase of the same flashlight because the rubber end to turn off and on has worn out after three years of continuous use. The flashlight itself still works great, if only they sold rubber replacement parts. My husband is a CNV machinist and uses the flashlight to look inside the machines. It illuminates everything and he loves that it’s rechargeable. He’s dropped many times and has never needed a new lightbulb or has broken or cracked. It’s very durable so of course he requested the exact replacement.

Great flashlight. High quality and dependable.
I use this flashlight daily. I work in corrections on third shift and it is a go to flashlight. Streamlight is the best in the industry IMHO. Wish they used USB C instead of Mini USB, it would be easier to charge since I use USB C for just about everything else.

it's just that useful for me
Got one of these as a Christmas gift a couple of years ago. It's part of my everyday carry, and gets used every day in my telecom job, around the house, and wherever I might need a light. When I lost the first one, I bought the replacement that day, and had it overnighted, it's just that useful for me. Pros: Battery recharges via any handy micro-usb cable and charger, I often recharge mine in the car or off my laptop. USB port's cover is a built-in heavy sleeve with o-rings for weatherproofing. I've dropped it into 2-3 feet of water accidentally, and it didn't care. I wouldn't go swimming with it, though. Despite being a single LED, and a smaller one, it throws a LOT of light, and is painfully bright if you're too close to it. I very rarely want a bigger flashlight. Doesn't get too warm in operation, probably because it's built like a tank, all metal exterior construction. The rechargeable battery is replaceable if it wears out! I haven't needed to take advantage of this feature yet, but I like that it's an option. Downsides: Unlike the AAA powered Streamlights I've owned before, this is not something I'd want to carry in a shirt pocket, it is quite a bit bigger. Fits fine in a cargo pocket or even a regular pants pocket, though. Does come with a belt loop carrying thing, but I found it annoying to use with the light was bouncing around on my belt. Probably not a bad thing if you're used to carrying tons of stuff on your belt (law enforcement, EMT, Batman, etc), but I didn't see it as anything other than jacking up my Everyday Carry Nerd Cred points. The finish does seem to wear on the edges of the light a lot faster than it "should", but that may be due to how I'm carrying it. Some people might find this to be a bad thing, I think it makes it look well-used and give the tool a bit of character (I'm weird like that)

E.D.C. Pocket Light that Deserves its 4.5 rating
Purchased in Sept. Of 2019 and it has been my e.d.c. pocket light ever since. It has served me as a work light and an emergency light. I work in a pellet mill where fine dust is abundant and I can say I have never had any issues with this light. I have used it at night looking into bins and cyclones checking for product/foreign objects as well as viewing of less lit area's. The hot spot is very pronounced up close but further away you have a nice wide clean beam of L.E.D. light. It has been an emergency light for a few power outtages and with the lights lightweight pen-light style, it fits easily and comfortably in a pant pocket or a shirt pocket. You will notice it more if it's in a shirt pocket. I've clipped it inside shirt collars before for quick access and under those situations, it did not bother me any and in fact, It worked out very well. Water resistance. To brag on the waterproof seal, yeah, I wash my work clothes and I forgot to remove it the other day from my pants pocket. The light got washed on a normal spin cycle and works fine. Still holds a charge like a champ - it's just cleaner than it was a week ago! I generally do a pocket dump and everything comes out and how I missed it - well, Fate had it that this review needed a waterproof test so, here it is. For the drop rating, I've never dropped it more than 3-4 feet. It has very few scratches and has never broken. The pocket clip and I have had our rounds tho. It pops off easily and I just have to remember when I sit in certain chairs or vehicles to be mindful of that. But when it pops off, it easily pops back in place. They also sell replacement clips just incase you lose or break the 1. The battery life, what can I say, I charge it randomly unless I use it heavily at work. There has been a few nights where it was used constant on for long periods of time, forgive me if I don't remember, but it does grow dimmer as you near completely draining the battery. . . But I could charge it back up at my desk and for the most of the times, this light holds the charge in my humble opinion, extremely well. After all is said, I would buy this again and I would recommend this light if you needed. It has never let me down and I give it a 4.5 because there's always room for improvements. Pics are taken at the time of this review. Actually, I'd probably buy another and review it on my socials. Find me @ Big Mo Country on YouTube and Instagram and subscribe and one day you may just see this flashlight in action!

A must have, awesome light !
I recently purchased this penlight and I am extremely impressed with it! This flashlight is compact, lightweight and easy to carry in my pocket, yet it produces a surprisingly bright and clear light.It has 2 different brightness settings, it’s rechargeable, and waterproof! I once dropped it in a gas tank and wasn’t able to retrieve it for about 30 minutes. It didn’t turn off, stayed totally dry inside and worked fine after (Though I don’t recommend doing that lol) I use it for everything from working on my car to taking my dog out for walks at night, and it always gets the job done. Overall, I highly recommend this penlight to anyone in need of a reliable, high-quality flashlight. It's affordable, easy to use, and has quickly become one of my go-to tools in my everyday life. Great product!
