I’m initially very impressed with this sight, especially for the price. I’ll reserve judgment on durability for later (and will update this review accordingly), but the rugged build quality, mounting fit, very clear lenses, and extremely sharp reticle are all extremely good. I wish it were available in a green reticle as that is my preference (supposedly coming available), but this has the clearest reticle for my personal astigmatism out of all my many red and green dot sights. The only other reticle that probably bests it is in an Eotech Vudu LVPO, although that one is also etched so perhaps not the best comparison. The shake awake feature also works precisely as described, turning off at exactly three minutes, and coming on instantly at the slightest touch. If it holds zero, remains durable, and the battery life is as advertised, I’ll likely purchase more for other pistols. At this point, highly recommended!

Super impressed with the Osight SE red dot. I put it on my P365 and installed quick and easy. Love the fact that it has a multi reticle. Super rock solid body, didn't deform at all when torqued to proper spec. Glass is clear and there are lots of adjustment settings for brightness as well. Also love the shake awake feature, which totally helps to conserve battery life. Solid optic for a great price. Highly reccomend!

Ok let me start by saying I am an optic snob....I'll admit it. I always tend to go for the proven/more expensive option. That being said this is by far the best bang for buck optic on the market, hands down. This will blow any trijicon, holosun or sig out of the water. If you are on the fence as I was, just do it, you will not regret it. The optic itself is exquisite and has all the features of a $3-400 optic, and on top of that it comes with more goodies. I came with tools and a complete assortment of mounting screws. It's easy to use and battery life has been outstanding. I have so far beat the crap out of it and it comes back for more, no breakage and no loss of zero. Fyi mounted on p365xl Bravo osight, this thing is awesome

Can't say much except what others have said. Only wish I'd have grabbed a couple when I first saw them at like $140-$150 I think. Steadily saw the price go up like $10 every week as they got more popular. I saw it hit $180 with a coupon that brought it down to the previous weeks price and jumped on it. Now $200 as of this review and I'm sure it will go higher. I'm not really a fan of their flashlights but, this is an impressive little piece. Super small footprint and super low deck, despite being a side loading battery that sits parallel with the slide. Impressive. Most optics that sit this low would have one of those goofy perpendicular battery boxes that sits on the side (or even the top...) and sticks out like a thick quarter in your visual field... or worse yet, a bottom loading battery. But yeah, nice flush fit, side battery tray with screw cover and I really like the uniform width. Some optics have a shape that kind of starts one dimension and then flares out up front, which is cool sometimes but I feel like with an optic really designed for a micro compact carry gun, it should be as low pro as possible. I'm sure we're just getting started with tech like this and these will be antiquated within 5 years but maybe not... the RMR is still around and hasn't changed much in like 15 years and people still buy that bulbous expensive bottom loader despite all the other great options out there. I am a huge fan of the multi-reticle and I would definitely recommend it to ANY shooter because you can change it to fit your style but I would especially recommend it to shooters who are new to shooting red dots. I'm fairly new to red dots myself and having that circle dot really helped me get used to drawing and snapping in to the sight picture fast like it should be instead of spending a lot of time looking for the dot like most RDS newbies do. Of course the better fundamental is to try and pretend you have no dot and just punch out normally, trying to pick up your irons but it's not quite as easy as it sounds. Having that option of a larger reticle footprint that's super easy to pick up but still have great accuracy potential as opposed to just a huge solid dot is awesome. Then as you get more used to shooting with a RDS, you could transition to just a dot if that ends up being better for you, or you might just find you like the circle dot. I am actually finding myself enjoying just the big ring with no dot right now for close up tactical type shooting. My eyes seem to be able to tell my brain and body to shoot pretty accurately with it and there's no obstruction from the center dot and super easy and fast to pick up. I always liked a really wide notch rear iron with a really skinny front so I got lots of light and visual coming through. I actually shoot that style more accurately than the the traditional "target" sight setup which is to basically have almost no light coming through your front and rear alignment. I guess my brain is kinda backwards. I also prefer the red color over the new hotness that is the green, unless it's actually a projected laser dot sight ,but that's really only because of the fact that you can actually see a green laser in the daytime and most of the red ones are nearly impossible. Anyhoo... that got a little wordy. Oh well. Yeah, it's a good little sight, very clear, co-witness on my hellcat pro shows probably close to 75% of the sights from the top edge and they don't come with super tall sights so that's pretty impressive. I still haven't really decided if I wanna EDC with a RDS but this is definitely the one I would choose if I do. I carry appendix style pretty low pro and I dont wear undershirts so I would definitely want it enclosed but if you're more of an OWB carrier it wouldn't matter as much. I have a bunch of different open reflex RDS but this my first closed one, and I gotta say, I'm sold. They should pretty much all be enclosed like this I think. Maybe even sold with replacement windows somehow...IDK. BTW, if you're not hip to all the stupid acronyms, don't worry about it. Here's a translation matrix of a few of them: 1. EDC= everyday carry. The gun and or other weapon or defense tools you carry everyday. 2. RDS= Red dot sight. Also sometimes called MRDS= miniature red dot sight which are the size usually found mounted to pistol slides. Some also call these RMR's as a blanket label but RMR refers specifically to the offering from the trijicon brand that was basically the first one that anyone mounted to a pistol with a reciprocal slide. It stands for "ruggedized miniature reflex" sight. Reflex is the type of sight that basically has a reticle of light projected from a small emitter on the deck onto the lens. 3. OWB= refers to holster/carry position, "on (or sometimes "outside"the) waste band" 4. IWB= inside waste band. This can be many positions around the circumference of your waste and is preferable for more discreet concealed carry. 5. AIWB= this term specifically describes the "appendix" style of in waste band carry which positions the gun low, just above the belt line and either just left or just right of the buckle. Usually whichever side your dominant hand is. There's tons more but that can get you started. I hope this can help someone.

I have been buying only OLights since I was introduced to them at the 1999 ShotShow. The first one I bought still works like the day I bought it. So when I just found this jewel I had to buy it. And wow for the price it is half the price of the high end units and work the same. Almost as small as a rmr Comes with screws for any gun you could possibly install it on. Works absolutely great and shuts off in 3 minutes by itself. Says it has a 85,000 hour battery life that remains to be seen. But if using on your edc gun it will need long battery life. The battery last the longest if you keep it on the dot. Which I like. Very nice setup,high quality and from experience, a very good company that stands behind their products. Even though I have never had to replace anything and I have at least 7 of their lights including their most expensive and incredible flashlight that throws a beam for 938 meters. I also have the other one that is a flood light and it works just as well. And I love the way they recharge but the cords could be longer. Their batteries are top notch. Like I said my first headlight and flashlight from 1999 still works and are just as bright today. So I am sure this product will last just as long as
