Great holo
5/5 stars "I'm blown away by the Ohhlion holographic sight! It holds zero perfectly, even after repeated use and rough handling. The fitment is excellent, and the viewing window is crystal clear. I love how it performs in both bright outdoor conditions and low-light indoor settings - the brightness settings are spot on. The sight is incredibly reliable and accurate. One thing to note: to turn it off, you'll need to either press both arrow buttons simultaneously or hold the NV button - a bit unconventional, but easy to get used to. Also, keep in mind that it takes AA batteries, which aren't included, so be sure to pick some up. And the best part? This unit is a fraction of the price compared to the brand name units, offering incredible value for the performance you get. Highly recommend this optic to anyone looking for a top-notch holographic sight for hunting, tactical, or competitive shooting without breaking the bank. Great job, Ohhlion!"

It does the job
I was pretty worried about the quality as it's only $38 right now, it actually surprised me though. My only complaint is that I wish it didn't have the "For Law Enforcement Use" on the side. I can probably sand it off, but otherwise it's a pretty solid EOtech clone. Keep in mind I am just running this on an airsoft rifle and not a real one.

For the price it's a great optic.
Overall I give the Optic 4 stars for a budget optic but 5 stars for the price range. you can spend a little more and get a Bushnell TRS-25, Sig Sauer or something along those lines however if you're looking for a good Eotech holographic clone on a budget or just for an airsoft gun this is a good choice. For the low price of $45 it's just a good looking sight on your rifle. I haven't tested to see if it holds zero on my AR yet but if you're looking to use it on an airsoft gun it's a solid build. The optic it's self is build pretty well for the price. The only thing I don't like about it is the glass is a little dark and reflective so the view out of it isn't perfect. If it weren't for that I would say this is the best budget optic under $100. For the $50 price range though this is probably the best you're gonna get. I'm genuinely surprised.

Not terrible, not great
I mean, it's a 40-50 dollar Eotech knockoff. You're getting what you paid for. Pros - - Decent sized sight picture - Battery seems to be holding up. I've left it on for several days on accident. - fairly easy to sight in. - actually seems durable. Housing feels pretty solid. - Easy controls. Cons - - sight picture, while decently sized, is not particularly clear. It's definitely off colored and a very dark. - It's a large optic for it's class and it eats up a lot of rail space. - The deal breaker; The redical brightness is FAR too low for the outdoors. If you're shooting in low light or let's say - playing airsoft or what have you, it's fine. In doors, it's okay as long as your environment isn't super bright. As soon as you go outside, good luck picking up your redical. On the brightest setting it's barely visible. With this being said, I'd give this thing a 3 to a 3.5. Again, not horrible for the price

Low Parallax & Brightness
I really liked the build quality of this optic. My friends highly encouraged me to stay away from cheaper value optics. I believe that I would have been better off with iron sights at the end of the day. Issues: The parallax of this optics is quite off. As you move from side to side the optic is not able to stay on target. The brightness in normal daylight is weak. Luckily, the green color was visible at peak brightness. The optics reticle is blurry. It can be difficult for the eye to focus on. Summary: I think that this optic is a great attempt at a solid optic, but overall lacks refinement. The aforementioned issues prevent me from trusting this it. Truly the lack of parallax is my only real issue.

Buy at your own RISK!
Finally had a chance to take time to write a review. When the package arrived the sight was missing a battery. So had to buy batteries off amazon since no local stores near me carry it. Then after they finally arrived, the sight still didn't work. So that was a waste of money. AND BTW, the glass is tinted like the reviews have said, so if you are wondering if its bad, I can tell you, if you want glass that is clear, I suggest getting something else. What a waste of time
