VortexOptics Defender-CCW Micro Red Dot Sights - Motion Activation with Auto-Shutoff, Shield RMS Footprint, Fast-Rack Texturing - Unlimited, Unconditional Warranty

This red dot reflex optic is really great. Easy to mount as it comes with multiple options (mounting hardware) for different models of firearms . Good job Vortex! So far this site has worked flawlessly. The shake awake feature has not failed. The battery is easily replaced and accessible. Thank you Vortex for including a tool to unscrew the access port. Can’t say enough pros about this unit! Price point was on same level as other red dots with same features.

This thing is amazing, accurate, clarity is perfect and functionality in both daylight and with polarized glasses! Stay away from the red dot if you need to use this in any kind of daylight or use sunglasses, this green dot is a game changer!

I like this red dot quite a lot. It was super easy to mount on my hellcat. No additional hardware needed. The controls are fairly intuitive and kept to the basics. i’m thinking about buying a second one. Highly recommended.

I bought this sight for my PSA 9mm Micro Dagger. Not that there are a ton of RMSc sights on the market, but this is a pretty good one. Out of the box, this optic was very accurate, about a 1/2 inch low at ~20 yards. Very easy to zero in.There's a pull tab to activate the battery, but mine tore with the battery cover screwed in. It wasn't clear in the installation instructions that the battery cover should first be removed, or at least this was the case for mine.The shake-awake feature on this sight is VERY sensitive. With the Dagger placed flat on the counter, it seems to activate just with heavy walking. It's definitely important that the motion sensor be sensitive, but maybe not so sensitive that it's responsive to vibrations. If you use this with your daily carry, I imagine it'll almost always be on for most of the day. Could be a lot worse, but this'll definitely impact battery life. I read other reviews talking about the excessive 14-hour auto shut-off. My manual says that that's only after it's initially powered on. I believe it shuts itself off after about 10 minutes.The screen size is great while still staying fairly compact. The red dot at the highest setting is way too much for me and affects visibility of the viewport. One level down from the top was perfect for me.Tip: set your desired brightness with the up and down buttons, then hold the up button for 3 seconds to lock in the brightness and disable the buttons to prevent accidental presses.

You can’t beat Amazon for excellent Vortex quality optics for you firearms.

I've been using mine on my EDC for a year and a half. I have only changed the battery once. It has held its zero without adjustment since day one.

So far I have no issues with this dot. There is plenty of competition in this price range but I trust Vortex to have a good quality product. After a hundred or so rounds, it has held zero. And one note I'd like to mention, a lot of the reviews say the dot turns off after 14hrs then will shake awake. Mine shut's off after 5 minutes of no motion which is more appropriate for the "shake awake" feature. This must be something they have recently changed.

Looks great, no damage, it came in the box with nothing missing. I’ve got a Glock 47 I’ll be mounting this to. Be mindful: if you’re a noob like me, check the footprint on your MOS and see if you need a DPP mount like I did before you buy.
