Perfect EDC pen light
Streamlight is one of the best in the business and for good reason. Rock solid construction and a perfect level of illumination. I use my streamlight stylus every day. So far still on the first set of batteries and I anticipate long battery life. Fits perfect in shirt pockets or in most pen/pencil pockets. I have heard people say the button can be difficult to fully click for continuous use, however I find the resistance to be quite useful as sustained use is rarely needed for my use case. When needed however the button does click into a continuous use mode. Overall the best EDC pen light I have used.

Your best little helper EDC packs a PUNCH in a lightweight, compact, durable rechargeable EDCšš½
2-year review: STILL my #1 EDC flashlight! I wish I could give 10ā's out of 5 because I would. From the insane durability to the high quality case and body; to the rechargeable battery to the perfect fit! šš½ This hits every mark I had and some I didn't even know I needed. I work in a rehabilitation center and regularly get called to search for "contraband" in tight places. This little guy has never failed me. It is so bright I often only need the low setting to get done what needs done. The charge lasts for hours -even on high! Overall I have no complaints. The only slightly negative thing about it, and this is just preference- is the micro USB instead of the USB-C connection. But I bought this over 2 years ago so it may have been updated since. The brightness is 5ā, weight is perfect and case(body) is durable metal, also 5ā. The kicker for me is how compact it is for such a great, would, rechargeable EDC flashlight. 10ā/5šš½

Excellent Product!
I've only owned the pen light for a couple of days now, but so far I love it! I've gotten used to carrying a small LED flashlight around with me. It's amazing how often a flashlight comes in handy (looking for something on the floor of a movie theater, on the floor of your car, etc...). It's just a great tool to have. LED light is so bright and clear, it really helps you see more than traditional lights. It's such a step up from the old yellow flashlights of our past. I bought two small'ish high quality Leatherman flashlights at Costco for $25-$30 each. I also bought two not-so-high quality flashlights at Sam's Club for $28 (package of two). I'd either keep one in my car or take it with me when I go wherever I went. Therein lies the problem. Carrying a flashlight, especially a well-made one (i.e. heavier), is a pain. It's very difficult if you're just relying on your pockets & hands. It's easier if you carry a backpack or a man bag, but that's not always practical. Anyway, a flashlight was always just another thing I had to carry (iPod, Flip video, cell phone, wallet, keys) wherever I went. Living in the Midwest, we have very cold winters and very hot/humid summers. I'm not a fan of leaving electronics in freezing or sweltering vehicles, so I always have to truck everything around with me. Well, thanks to this pen light, I have one fewer thing to carry. Sure, it still has to go with me, but I hardly know it's there! Obviously it's the size of a pen, so it's very small. It's also very lightweight. The light is extremely bright, much more than I'd expect from a product this size. Just stick it in your pocket and go. It feels like it's very high quality, and will hold up with more than a few drops (not that I'd recommend dropping it, but it happens). Be careful with the holster. It comes very tight and will grip onto anything. At the movies this weekend, I ended up using the light for something, and then attached the holster to the leg of my shorts. When I stood up (and the light stayed firmly in place), I decided to pull it off my shorts leg. I wasn't thinking. Make sure you gently slide it off whatever it's clipped onto. I ended up pulling it out more than sliding it down, and it bent the holster out a bit. Now it's not as tight as it was when it came, and will no longer grip onto just anything.

This flashlight is a very well made tool.
This is one of the best pen type flashlights I've ever owned. It's bright and doesn't eat up the batteries like most. I've had the blue one for over 6 years. I lost the blue one a couple years ago. Then ordered the silver one. After the silver flashlight arrived I found the blue one in my driveway. My truck ran over it and it was sunk down in the gravel and dirt. Took it in cleaned it off and worked fine, didn't even dent it Missing about two weeks. It's lightweight and waterproof. What I liked about it is I wear overalls all the time and it fits comfortable in my bib front pocket along with my pocket knife. I always have it with me and has come in handy hundreds of times I don't leave home without it. As for buying it again, just as soon as I thought the blue one was lost I re bought the silver one. I won't go anywhere without it. It's a durable product well worth the money.

Great small light
So far this light has impressed me. I use it daily(had it about a year now) as a career fireman, and no issues. It lasts a decent time between charges, usually plenty bright on the low setting, and itās tough. Recently it fell out of my pocket in my gravel driveway, before I realized it was missing I ran over it with my pickup. It suffered a few cosmetic marks, but still works fine.
