I am very impressed with the Osight SE its a quality build! The red dot is very clear with no distortion on all 3 sight settings (dot, circle, circle dot) and is more clear than my Holosun 407 and 507. The glass is also very clear and offers a larger field of view than the Holosuns. It was easy to sight it in and holds zero with no issues. Huge improvement being an enclosed sight and is alot easier to clean the glass for EDC. I will be switching over my other holosuns to the Olight SE. I wasnt a fan of the S model bcuz of the large block charger and am so glad Osight came out with the SE and its using a replaceable battery on the right side of the sight. The shake awake feature works as soon as you pick it up. The brightness settings are easy to change and work great even in the brightest lighting situations. Comes with every mounting screw needed and instructions on which to use based on the firearm. Osight really did a GREAT job with the SE and you cant beat its price point! I highly recommend this sight!

I was so impressed with the performance and price that I bought a second one and luckily it was on sale. For an enclosed emitter (ideal for CCW, no lint or dirt inside the emitter), this costs about half as much as the competition, hard to beat! The lens quality is top-notch, and the red dot is crisp and sharp. I would say, this is better than my Holosun optic equivalents. Packaging is also well thought out, it includes all necessary screws with Loctite pre-applied, plus spares. Most importantly, if for some reason the red dot fails, it co-witnesses perfectly with both of my primary EDCs: the P365X and the G43X Gen5 MOS. I might be in the minority here, but I actually prefer that it doesn’t have auto-brightness. I like being able to manually set the brightness and leave it where I want. After 400 rounds, zero has held perfectly and the dot remains just as sharp as day one. No complaints!

This is my first pistol dot, so please keep my inexperience in mind - But, it seems great thus far. Mounting was easy with the included hardware. The dot is crisp to my eye (and I have an astigmatism), and it's holding zero after several hundred rounds. The fit and finish look quite nice, and presuming that the material (7075 aluminum) is what they claim it to be, then it should be more than tough enough. It's hard to find a multi-reticle dot at this price, let alone an enclosed one. This thing has been a win thus far for me.

I am super impressed with this dot. The cost is great, it comes with everything you need, and its supper easy and cool way to charge the sight. Its built very well and after shooting with the correct screws and Loctite it wasn't loose at all. I a very happy with this sight and how well it is made. I bought another one right away for another firearm. The larger one I have has a awesome window and the smaller one has three reticule options which I love. The smaller sight does use a battery but the larger sights have the charging house that you can charge and put on the sight when the battery is low.

As an owner of a holosun eps carry Mrs, I was intrigued enough to purchase one of these to compare it to at roughly a third of the price. Took it out to the range today to get it dialed in. I was wondering why I was struggling to get my left right windage. After approximately 80 to 100 rounds, the unit stopped working. As I start to evaluate, I realize that the battery tray is completely missing. It appears that due to the battery tray screw and the left to right windage screw being nearly right next to each other that I was most likely adjusting the battery tray screw. Luckily they give you two extra screws for the battery tray and that I was able to find the battery tray in the weeds. I am giving it four stars mainly based on the fact that the design could have made the battery tray screw on the front side of the optic instead of right next to the windage screw to alleviate any issues such as this. As far as the optic is concerned, the glass clarity is excellent. The construction overall is also excellent. I would definitely purchase another one of these but I would like to see them change the design a little bit and flip the battery tray screw towards the front of the optic. Holosun puts theirs in the center at the top with a slight bulge to differentiate the locations of their battery tray, screw and windage adjustment. Overall anybody thinking about trying one of these out, you won't be disappointed. Basically just pay attention to what you are adjusting because it might be your battery tray screw and you may end up losing your battery tray depending on where you're shooting.

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
