Great for the price. Sturdy enough for me.
Works great on my 19x and I’ve dropped it and definitely ran well over 500 rounds and I lost count but still holds zero and dings the steel. For the price I prefer it over my $300 holosun.

Not terrible. Surprisingly decent
Not a bad budget optic. Came in decent package, tools, batteries, lens cloth. Solar functions well.So far so good. Held zero on 9mm after 100 rounds. Will let more time elapse to do a more in depth review. As time will tell if this is a quality optic or not.

Great Value
Ohunt does a very good job of copying popular tech. This is good enough for home defense in that the shake awake works, the dot optics are crisp and clear, and holds zero and adjusts consistently. Mounting and casing are hard and the finish resists minor scratches. I have mine installed on PCC on the included riser mount. The glass is clear enough and the parallax is not perfect but not bad enough to miss your shots. All similar offerings are 100$ more . If you want to try a multi reticle enclosed emitter optic, this one will get you started. Suitable for up to 300 B/O & 9mm. Fantastic for any and all laser/airsoft applications. I got mine on sale for less than 100 on pre order .

I’d Skip this one
The shake awake feature worked. This optic is more geared towards a full-size piece or a long « piece » (not saying the word to get me shadow-banned). I did not like this because as your head moved (+/-5 degrees) the dot would move as well. That was very concerning to me. If you sight it in and you « make ready » again but not as perpendicular as the sight-in, the end result could be off. My other dots do something similar, but this was WAY more pronounced. I had to send it back.
This red dot is reliable and durable Holds zero On my FN 545. It’s a little big but I love it. Way easier for you to pick up the dot visually I’m my opinion. The shake wake and solar panel is the cheery on top. highly recommended. –
At the price point, it is very reliable
The red dot is reliable and durable. Hold zero just fine on my FN 545 300 rounds through. Love the solar panel and the shake week technology those were just the cherry on top. You don’t have to worry about all that Dust and hairs falling into your emitter since it is enclosed on this one. Very nice!!!
