What a great optic, well made, excellent red dot, easy to adjust and bright! Only con, no SAE mounting screws, only metric included in the packaging. Otherwise, great optic for the money!

I was looking for a sight that would fit my Dpp sight plate on my Taurus g 2c 9mm. It fits perfectly. I went and shot a hundred rounds with it, had no problem. Its about time to find something at a good price that works this damm good. I will buy one for my 380. I do say if you're looking for a red dot this is the right one for the right foot print and price. It looks really good on my gun. Very satisfied.

Not a bad little sight. Battery life could be better but fit perfectly on my Taurus GX4. Did need a little lock tight to stay firm. But once cured kept 0. I didn't see in the reviews the battery type it's CR1632 for those of you looking. (If it's in the manual I dunno as I didn't get a manual in my box) For the price and quality not bad at all. Shake to wake is a little iffy as I found battery drained quickly my guess is when I stored it being on it's side may have triggered the wake. Can't verify though.

Mounted good. Feels solid. 3rd time to the range and it’s dead. Maybe 300-400 rounds thru it. In the middle of shooting today the red dot would turn on and off with shots. Shake the gun and you could watch the dot flicker. DO NOT GET THIS DOT! Spend more money and get a better optic. Out of window to send back. If the seller wants to warranty this I will update accordingly. ******update****** No contact from seller…. Was going to take this off and got too looking it over. Couldn’t find anything lose. No noises when I shook it. Took the original battery out and put a new one in that I know is good. Took it to the range today and put 200 rounds thru it without a single complication. I just needed to put rounds thru it wasn’t really worried about accuracy lol. Maybe it was just the battery? This isn’t my main toy, just one I picked up to add into my rotation. It’s mounted to a CDS9. Mounts up just fine. Looks decent. I don’t think I’d trust my life on this optic but it may be good to break them in with. I’ll put some more rounds thru it and update. Another Update….. Made contact with seller. They shipped me out a new dot. Had it on the firearm for a couple months and put around 500 rounds or so thru it with no issues. Went to the range yesterday and 1/2 way thru it shut off. Messed with the battery cover and couldn’t get it to come back on. Got home and it was operating again. Not sure what’s going on but this is 2 with the same issues.

So far works great on a 5.56 pistol

This only my 2nd red dot (my other one is also an inexpensive unit that works perfectly on my Ruger Mark IV), so I can't really compare this sight to the expensive ones. That said, this thing has shake awake, excellent brightness control, and battery access on the top. I've put a few hundred rounds through it on my P365 9mm, and the zero has stayed true. For me, this thing absolutely ticks all the boxes, and at $60 it's pretty hard to beat. Not sure what additional features I'd get with a $200 - $300 red dot other than a much lighter wallet!

Was great when it was working. Held zero for the most part then out of nowhere just crapped out on me and even changed batteries. This happened on my 22LR pistol so if that can make it not function don't bother putting it on a higher caliber.

So far this thing is a great deal! I only have a couple mags through it, but the sight holds zero well! Impressive coming from a 60 dollar optic! It’s plenty bright with the brightest setting just a little blurry in med to low light situations (I have a slight astigmatism in my left eye). It was a breeze to install on my Taurus GX4 and it came with all the necessary accessories to fit multiple firearms. The fit and function isn’t top notch, but again for a $60 optic it’s fine. Overall, this is an excellent value and worth every penny!
