I put this on my airsoft gas pistol and am very pleased. The sight sits low and it is easy to acquire the dot when aiming. The adjustments have a soft barely noticeable indexing that I wish was more noticeable. That said, once adjusted held its setting just fine even with my replica being a gas blowback model. The shake awake works as described and activates as soon as you move the unit its attached too. Really a great deal for how well it's made and performs, better than risking higher end optics to BB damage.

Change the battery twice. Red Dot Fades out after shooting only a few rounds like the battery is going dead. Don't know why then works fine. Then does it again

This is a very nice reflex sight, perfect for a pistol, PCC, or shotgun. I find that the view window might be a little bit small for an MBR, and you'd have to get your own riser. The dot itself is very crisp, and getting it calibrated is easy enough to do with the supplied tool. I use a laser bore sight tool and make the dot line up with the laser, and this always gets me on paper right away. I then fine tune it when actually shooting at the range. Using a red laser and green dot makes it especially easy to do. Installing the battery, which was included, is also easy to do, though you do have to take care when putting the battery cap back on, to make sure you don't get it cross-threaded. The only thing I did not like about this product, and it was not enough to take away a star, was the included cover. It appears that the silicon cover they provided might be for a larger gun sight, because it fits lose and has a large gap in the front portion. All in all, a very solid performer, for a very reasonable price.Five Star Value Priced Small Form Factor Green Dot Reflex Sight

I’ve been using the ohhunt RD U2 Shake Awake 3 MOA Dot Sight, and I’m seriously impressed with its performance, durability, and clarity. It’s a fantastic budget-friendly alternative to higher-end optics without sacrificing quality.Key Highlights:🔹 Crystal-Clear 3 MOA Dot – The dot is sharp and bright, with multiple intensity settings that work well in different lighting conditions. No distortion or excessive blooming.🔹 Shake Awake Feature – A huge plus! It turns on instantly when motion is detected and powers down when not in use, helping conserve battery life.🔹 RMR Footprint & Picatinny Mount – Super versatile and easy to install. Fits perfectly on my setup without any hassle.🔹 Durable & Lightweight – The aluminum housing feels solid, and it holds zero even after repeated recoil. Works great on pistols, rifles, and shotguns.🔹 Affordable Yet High-Quality – For the price, it competes with much more expensive optics and performs exceptionally well.Pros:✔️ Sharp, adjustable dot brightness✔️ Sturdy and lightweight design✔️ Shake Awake for battery efficiency✔️ Easy to mount and holds zero✔️ Excellent value for moneyCons:❌ None so far – just wish I had got another one for my other setup!If you’re looking for a reliable, feature-packed micro reflex sight at a great price, the ohhunt RD U2 is an excellent choice. Highly recommend!

Green dot is very visible in day light.Easy to adjust, sturdy construction, strong connection to rail.Only reason for reducing star is the amount of name brand sights that have been out for awhile that are also in this price range.

Picked this up for a range toy build I've got going. Seems to be a decent quality red dot, although it doesn't compare to my Trijicon, Aimpoint, and EoTech sights. This is a basic range worthy red dot that seems to be fairly durable for basic use, however I don't believe it will hold up to the battle ready sights I've used in the past and the heavy duty sights I currently have on my daily use weapons.This sight has a nice field of view, clear optics, and a dot that doesn't seem to be impacted by parallax for the most part. Multiple brightness settings are available including two night vision settings that I haven't had a chance to test with my NVG's, but will in the future and will update the review if I run into problems.As with other "shake-awake" sights I've used in the past, it must be turned off unless it's being used since any weapon carried in a vehicle, pack, bag, or holster is going to be moved around and the sight will be constantly on, draining the battery in a quick fashion. Works great on a weapon that will be kept in a safe, closet, or nightstand. Overall a decent sight for the money.

Reasonably good quality red dot. Fits rmr footprint mounts. Looks good and shake awake function is nice for those looking for this function. Overall a great price for what is a good entry to mid level optic.

This has surprised me for its quality and build. Has held zero and functions perfectly. Glass is clear and fit RMR footprint plates perfectly. Very low deck height which still allowed for stock irons to be used.Only downside is the "shake awake" feature. It works as it should but the dot returns slowly. There were instances where I picked it up and the dot was still coming to brightness. Would not recommend for Duty use but perfect for targeting and casual use
