This is well worth the money. Every feature is as-described. If you're used to the off-brand sights, you'll be a believer in Holosun after buying this. The adaptive brightness is amazing. And any movement turns it right on. Great utility.

Really enjoy this on my Springfield saint pistol. This is running on a short barrel .223 pistol and it performs very well. Easy to adjust with the built in turn caps to dial it in and the always on feature and auto off are a no brainer to reserve power. In addition the anticipated battery life is stellar and looking forward to getting many hours out of this unit.The dot is clear and crisp which makes targeting and keeping a tight group easier but the ability to crank up the brightness is nice in case of a bright day to still clearly see the dot in any environment is great.So far no functionality issues and mounting seems rock solid. I would definitely tell a friend to have no reservations in buying this compared to the over priced aimpoint scopes. This hasn't been tested over the long haul but it seems to be of solid construction.Great piece of hardware and if I have a similar gun philosophy I will likely put this same scope on that gun as well.

Package came a day early- that's always great! Out of the box, I was immediately satisfied... Solar power was on instantly and the red dot was bright and crisp. This came with the taller mount already on it and I installed it on the pic rail in under 30 seconds. Mount feels lightweight but plenty sturdy and sits tight on the rail. The red dot is set up as a 1/3 co-witnessed with my flip up irons, and the sight picture is really good. The red dot is washed out in the picture that I provided due to auto focus on my phone, but rest assured in person, it's crisp 2 MOA... Glass is clear- dot is bright and crisp, unit adds very little weight to my rifle. Based off of this initial impression, I am very pleased and feel like this is a great buy for the money. I still need to get to the range and use this thing, but if the remainder of my experience is as good as my first impression, this red dot is the real deal.

The Holosun gunsight has been great on my 16" AR-15 carbine. I have shot it in low light and in direct sunlight and it always is set to the perfect brightness for me and I have not ever had to use it on battery powered mode. The construction and function of the sight work well for me. It's not going to be an Aimpoint Micro replacement, but still provides incredible value. The front lens of the sight is angled away from the center boreline making it less reflective. The included high mount gives a perfect 1/3 lower co-witness.I have two main complaints about the sight. The first is that the dot blossoms and is not really 2 MOA. I have tried on every brightness setting, but the dot is never as crisp as on an Aimpoint or EOTech. At a fraction of the cost, I can accept that but just want to let other people know. The second complaint is that the adjustments are not marked up/down and left/right. You have to flip the adjustment protective caps over then the up/down and left/right adjustment markings reveal themselves.

Got this at a great price. Out of the box the sight was on and was visible without a battery. Vary impressed. Mounted on my ar15 and it looks great. It's a 1/3 Co witness and easy to shoot through with iron sights. I had a concern at from the start because the battery compartment wasn't like the picture. It was a slip on battery holder unlike the picture with the 2 screws. But after contacting the company they said its the newer model, and it is still water proof as advertised.Wile I was messing with it I noticed that there are 3 settings on solar power. It will auto adjusts so the ambient light and pick a setting. On manual it will go from barley visible to a giant red dot that is easy to pick up. Looking into the dot it's not a perfect circle, more like a real small line but not as noticeable unless your really looking for it.After I Co witnessed it I went to the range and it held zero great, shot out to 400 yard with out a problem. 5 months later and about 700 round , it's still kicking vary impressed and will keep testing it and updating as time goes on.The only con I have is that it won't take normal t-1 risers but the one it came with is solid
