I have had 2 aimpoints, both worked 100% all the time.
I sold my ML3 for a T1, and its been the epitome of reliable.
I have PERSONALLY seen 2 EOTech's go belly up. One kept on eating batteries (even though it was turned off. This is the signature EOTech problem) and another one (also ate batteries) wouldn't hold properly onto the picatinny rail.
There are numerous problems with the battery compartment (contact failure, battery draining when sight is off), problems with the rail clamp (a little less common), problems with the sight holding zero, and with the new 557's, problems with the reticle itself.
All the problems are fairly rare, but the number of different problems that PERSIST even after the Revision F, is scarry.
Yes, it is "new" technology, and it WILL gain reliability over time... But right now there is a treasure trove of problems with the EOTechs, that MAY happen.
Aimpoints... The ONLY time you will hear people complain about them, is with the dots being blurry, usually due to an astigmatism, or other eye problems.
AND the Aimpoint M4s is the new US Army CCO, NOT the EOtech
