I am extremely impressed with this sight considering it's price. I have tried several <$100 sights and this one is in a different league. I definitely recommend it. Here are some of my observations: Light weight, however it has a very solid feel with regard to construction and controls. It has a clear view through the optics with a slight blue tint. The red dot can be made very bright and it is well defined when set correctly. Two eye open shooting while using it feels natural. I've never had the battery cap unscrew inadvertently. It was easy to sight in and has held zero, however I'm only using it on a 22lr. I mounted it on a M&P15-22 with a Tuf Force 30mm cantilever ring and it co-witnesses the standard iron sights perfectly. Of course, if I was headed off to war I would get an Aimpoint. My friend has one and it is very nice. However, for my needs this sight is durable enough and I can't believe the quality you get for 1/5 the price. Hope this helps.
Pros: Solid feel, reliable, clear view
Cons: Included rings functional but cheap
