While the thread is certainly very interesting, the failure rate determined by the thread is probably quite a bit misleading. Folks tend to speak up and speak up loudly when they have a bad experience with a product or service, but much less so when they have a positive experience.
I recall from my marketing classes that a customer with a bad experience is five times more likely to tell others about his experience than a customer with a good experience. If you apply that to the ~20% failure rates in the thread, it would translate to something more like 4% to 5% failure rate, which is still significant, but not quite so extreme. I do like the thread, but I think we should consider the stat collection method before we let a big number scare us off. |
Well I had a 511 with "N" batteries that caused batteries to leak acid inside the sight and the sight would not come on. I sent it back and got the "F" revision and it did exactly the same thing. So I stored the batteries outside the scope and went to use it and it kept shutting off still after all this was done. I sold it-bought a new 516 model with CR123 batteries. Every time I shot it the battery lever would pop up and shut the sight off. I called EoTech and they mailed me another battery cover, it still did it. Sucks when you have a new $400 red dot and it had black electrical tape holding the battery compartment together––yea that's something i would take to combat 
I tried and had a 100% failure rate-even sent sights back and got parts and they both failed. I bought Micro Aimpoints and moved on down the road, they have been 100% |

Quoted:
If that were the case wouldn't the same principal apply to the Aimpoint thread as well? I haven't kept up with the threads but last I saw there was a significant difference in failure rate between the two threads. And your going to. AP while great & all that jazz are still a very basic redot. A holographic sight is more involved & has different power requirements. Almost all problems are battery related. |

I wouldn't disagree with that, but I havta ask.... is any perceived increase in functionality offset by the difficulties? For me, yes. Having a coolio "holographic weaponsight" sounds AWESOME until it shits the bed when you need it. |
I wonder what the failure rate of AR's is?

I would be curious if there is any data out there from other sources, primarily thinking the military. Be curious to see a actual tracked statistic such as: "of x purchased, x experienced battery related failures."
While I don't think EO Tech would ever be willing to release the data, I would bet an AR that the vast majority of the issues that they have had relating to batteries come from use of substandard batteries. Info like this would greatly enhance (or possibly hurt) their case, but I would bet it would be very telling. |

On a second note,
I do agree that the results were more than likely skewed slightly due to the market influences that were discussed, but I believe that the main takeaway of Zhukov's post was to get "actual experiences" with EO Tech failures. This forum has a habit of retelling stories like "I heard of a guy..." or "my brother's friend had this happen..." I think his post challenged everyone to look at how many failures have folks on the forums actually experienced first hand, and to provide a gauge with regard to specific models. |

Yeah I wasn't trying to stir the pot or anything, and I'm glad nobody jumped in and called me a troll :)
My main point is that we shouldn't come away from that thread thinking that one in five or one in ten eotechs that come out of the factory are defective. Disgruntled customers are going to flock to a thread and remember more of their experiences than happy customers. Someone with a bad product is going to have an interest in a thread like that, and feel an urge to post, whereas most folks will pass it by as they don't have any problems to report. It's also evidenced in the fact that with each respective page, the defect rate steadily declines. It is nice and quite informative to see a detailed list of the models and specific types of defects. Also it's nice to see that eotech has made significant efforts to address most of these problems in the XPS line. Hopefully as these newer units see more use we'll be able to have more data. |
| Considering the amount of eotechs in military, law enforcement, competition, and contracting around the world it's a little ridiculous to think they're not good enough for your range/"SHTF" gun. Although I will agree the N cell models aren't worth the metal they're made of. |

There is already a thread on the Eotech problem thread.
http://www.ar15.com/forums/topic.html?b=3&f=18&t=528448 Or is this a thread on that thread? I can't keep track. |
