I've had no issues with either thermal drift or battery life in my 512.

My EXPS 3-0's zero drifted by over 4 inches at 100 yards twice within a 6 month period without hard use, extreme temperature changes, or changes to the rifle. I don't know if it's a lemon or not but I'm returning it for the refund. Already have a T2 in a Geissele mount to replace it and couldn't be happier.

Haven't really had a problem with them at all, and if there is one thing Minnesota has, it's temperature variations! The only real problem I've had with the EOTech is the AA batteries invariably end up leaking in there and it fucks up the little grommets in the bottom of the battery housing, making them rust. I've gotten the little replacement thingies that slide into the housing, and those are great. And the EOTech does this with every Battery brand too. I really want to put those lithium AA's in there, but am afraid there might be a fire. All that said, I won't be buying another either. The aimpoint is a better system and the Leupold firedot is so incredibly more versatile I see no reason whatsoever to screw around with anything from L3 from here on out. |

I have a number of Eotech sights, various models. I also returned two Eotech sights that were powered by "N" size batteries. The battery life was problematic and they had parasitic battery drain when turned off.

I have an old one that takes the weird "N" cells. Works fine and seems to hold zero. I have to take the batteries out when I'm not using it because it seems to drain batteries sometimes, for some reason. Therefore, it's relegated to a 9mm AR range toy. I'd send it back to the maker but I don't want to wait 10 months for a refund.

It's probably overblown compared to drift on other red dots. There was a test done by a poster on another forum a while ago who found Aimpoints actually have even worse thermal drift than EOTechs. Trijicon's MROs did experience drift, but it was a lot less than both EOTech and Aimpoint, FWIW.
Full disclosure: I own one EOTech 558 and nothing from Trijicon or Aimpoint. I've had no real issues with the 558 holding zero. That being said, southern Texas' temps tend to vary from "hot" to "not as hot" so I'd probably be less likely to encounter drift than a state that has four seasons. |

I am a iron sights guy.
That said, I have had three EOTechs. My first one died on me the morning of my first LaRue Multi Gun Match. I had to shoot the whole damn thing with my BUIS, and the EOTech still attached. I currently have one on my SBR and one on my pistol that I haven't converted yet (yes, the tax stamp is in). I took my SBR to the range on a sunny September Texas Wednesday and I couldn't see the damn reticle for shit. I'm sticking with iron sights from here on out. |

We have a much more robust arms industry than we did decades ago and a lot of the stuff that SF ends up with is cream of the crop and stuff that the army is just too stodgy to buy for the regular troops like Glocks

My 558 gets so damn bright at the higher settings you'd have to be on the surface of the sun to not see it due to ambient light. Like it will literally leave an afterimage on your retina from looking at it for more than a half second and the whole housing is glowing; that bright. Generally two to four clicks up from the starting brightness will take care of a Texas afternoon for me, which is nowhere near full brightness. |

I had two. One of them had to be sent in to be fixed when the reticle got all wonky. They fixed it. I thought my ammo or my gun or my shooting was all messed up because every few months I would have to re zero my guns with eitechs on them. I'd go to the range and they would just be several inches off at 100.
Wasn't till after rote had announced that they had major problems that I put two and two together. I live in Alaska and would shoot in some pretty serious temperature differentials. I noticed an obvious issue long before they said they had problems. I just didn't know why. |

Probably wouldn't notice it unless it was in front of a magnifier on an accurate rifle. But that's where I had one of mine. I thought the problem was on my end. Seemed like every few months I had to re-zero that rifle. When the facts came out, it all made sense. Aimpoint T2 on anything with a magnifier, T1 2moa if no magnifier for all the things now. |

Deployed to Afghanistan for 14 mo back in 2011 with my personal 512 Eotech. Had no accuracy issues out to 600 meters at any temps i've dealt with. Same set of Duracells lasted me from 2011 to 2014 when they started leaking. Cleaned the terminals and threw in a new set of batteries. Looked like it got thrown down a really long driveway a 100 times after i brought it back from deployment. Green Beret friends ODA team runs them on there LWRC uppers. No issues, even runs one on his personal SBR.

I have 3, two have no issue, one EXPS-2.0 was sent back for R&R, and was returned to me within 2 weeks.
As for zero drift, I have no issue, but I am in South Kalifornia, my issue is more likely dust than temp extreme. |

They have a propensity to fail even when treated as safe queens. Delaminating reticles, failed electronics, failed nitrogen purging on guns that have essentially spent their entire life in a climate controlled environment.
I wouldn't put one on a toy, let alone a tool that my life depended on. |

Eo Tech paid a 25.6 MILLION DOLLAR fine to the US government for fraud involving their HWS and for knowing about their sights faults/failures and failing to report them as required in their contract.
Why anyone would buy products made by a company that purposefully and knowingly endangered our service members lives with substandard products for pure profits is beyond me. A 25.6 million dollar settlement and the companies own admission their products are failure prone yet they didn't report the findings as required seems pretty damn objective to me. |

I had two (down to one) EOTech 552s...I won't buy another.
I had both rebuilt by EOTech for being too dim in daylight conditions. Excellent customer service. Fresh back from rebuild, they worked great...but a couple of years later, and they're dim again, useless in daylight. No more EOTechs for me, unless they come up with something a bit more reliable. |

Mine has only lasted about 10 years so far so I don't feel qualified as to make a statement on reliability yet. I have to admit that while I was not a fan of it when I first got it, but after learning how to use it. I came to like it a lot. It is not intended to be used to punch dime size holes in paper at 300 yards. Real easy to get off a shot as you sweep by a target. It's all about learning to use the tools that you have. Not continually wish for what you don't have.

Pros: the fastest rds I've ever used. Much easier to switch between targets.
Cons: terrible battery life. Batteries will leak and eat the terminals. Glass delaminates. I owned a 552 for years. It worked for two of those years. Glass started to come apart and figured I'd use it anyway. Then the battery springs took a set which would cause the sight to cut out under recoil. I stretched the springs to fix. Batteries leaked twice, the second time killing the sight. When L3 offered a refund I couldn't box mine up fast enough. Some believers say "sf uses them, good enough for me". Problem is SF can pull a new one from supply, but I can't. A $500 sight shouldn't have the problems I had. If you still want one after the government lawsuit, don't cry when it craps out. |

I live in Ohio so this thermal drift stuff has dissuaded me from getting one, but I have always liked the style and reticle. Not a fan of the small window in theory but it never bothered me in practice when I did use them. I've always preferred Aimpoint either way.
