This may be an ok red dot sight for low cal firearms, but it does not appear to keep alignment on higher cal firearms - my sight goes out of alignment. Construction could be more solid -- There is a bit of play between the sight and it's mounting base and I have to readjust the site often. (I am not talking about play between the sight's and the weaver rail mount.) The sight adjustments work however they are not very precise (or sensitive) and have I trouble locking in and keeping it in position. I can shoot 50 rounds at the range and the recoil will throw it out of alignment every time. (I don't believe I am doing anything wrong adjusting it.) I took it to a local gunsmith and he said he could not adjust it -- but I really didn't understand that, because I can -- it just doesn't stay in adjustment. "You get what you pay for" and "use the right tool for the job" are two sayings that potentially apply in this case.
This sight may be fine for firearms like: airsoft and .22 cal pistols and rifles. However, .380, 9mm, .40, and higher (certainly P+), and shotguns, may not be the best platform for this sight. Your mileage may vary.
Reticles are good and brightness is adjustable, however you must remember to turn it off -- there is no automatic shut off (auto shut off is common with more expensive sights). Field of view on this sight is ok. Battery life is good, dies down a bit in real cold, but still works.
Bottom line opinion: IMHO this is a good inexpensive/cheap site for budget restricted consumer or lower cal pistols and rifles. If you have the budget you should be able to do much better for 1.5 to 2 times the price.
I hope this review makes sense and helps prospective buyers. Good luck.

So, you pay $30 for a relex sight. It weighs 4 ounces, it's rock solid, and it works great. What's not to like? I give it 5 stars because it's very inexpensive and does everything it claims. The only reason it doesn't have 4.5 to 4 stars overall is because people are, well, different. One guy rates it down because he didn't FEEL strongly that he needed it. And that's the sight's fault? Many others rated it down because they don't know how it flippin' works... Sigh. If you don't like this scope for $30, you're going to be very, very hard to please. Good luck with life. 8^)

I'm using mine on a POI Carbon 15. No issues. Zero'd fine, has kept it's zero. I have a Trijicon reflex on my CAR15 and I like the adjustments on the NcStar better; they're more positive. And I like the reticle and the lack of need for a battery better on the Trijicon. Of course, the Trijicon cost somewhere north of $400...

I was going to add some pictures but I see some very good ones have been put up since I looked last. Good job, and thanks for saving me the trouble!

Bottom line: Highly recommended. (revised sharply downward; see below)

ADDED: Review #2. I got another one for another rifle. Ah, now I see... the second one was more of a sight KIT than a useful item. After complete dissasembly, some fiddling around, some spring stretching, and careful reassembly it now works. I'm a technical by trade, and I expect that what I did will be beyond most folks. The first one worked great, so I gave it 5 stars. The second one didn't work, but I got it functional. One star. About the same time the second one started working, the first one slipped the detent in the brightness selector; now to see the aimpoint, you have to turn the knob to 1/2 way between two settings.

If you're looking for a military grade reflex sight this is not it. However, if you are looking for a sight that is affordable, functions well, and looks good, then this is it. Again, this is no high dollar sight. But, for the price, who cares... If you're using it at the range or for varmints then GO FOR IT! I have this sight mounted to an AK-47. It holds up to recoil well and maintains "0" even after 100+ rounds. I bought this sight through M1 Surplus. When I went to zero it in the first time, the elevation screw broke. However, M1 Surplus handled the return professionally and quickly (for snail mail). This is not a common problem with these sights. I generally buy these at gun shows because I can get them right away. But at the price M1 has them for, it doesn't hurt to wait a week or so for delivery. I can not give this 5 stars, simply because I had an elevation screw break. But, this is the only time that has ever happened. I have seen this sight mounted on everything from handguns to M4s, and everyone I know loves them. Including law enforcement officers on a budget. If you can afford an Eotech then buy an Eotech. But, if you're on a budget you can't beat this sight. It won't last as long as the higher priced sights. But, at the price, you can replace this sight several times over without paying the same amount of money you would for a higher dollar sight. I highly recommend both the sight and the seller.

Baought this sight for my Mossberg 500 for $[...] and was well worth it. I have routinley seen this exact make and model sell for $[...] or more at other websites. If the dot appears to be a bit on the dim side after a short while go buy a high quality battery. It is a fact of life that the batteries that ship with products tend to sit on the shelf for a long time or are low quality batteries. Most of the of the time companys supply them for convienence not as a selling point. With that said I had no problem zeroing in the sight the adjuments did the job and the adjument lock screws work ok. I had to tighten them down a little tighter then I prefer to, but They worked. The brightness controlls are decent. Personally I prefer a ittle finer controll over brightness, but it did the job well. The only improvment I would like to see is an auto shut off. I don't see how in other reviews there are complaints about it getting knocked out of adjustment with any thing larger then a .22 I use this on my shotgun with 2 3/4 00 buck shells and the sights stay in alingment just fine. If I fire rapid fire it will ever so slightly get knocked out of alignment, but then again so do I. :) Over all this is a great sight at a great price. I don't understand how others can sell the same exact basic red dot sight for 2x or more the price and stay in business.
