This will be unscientific, of course, but I am curious whether any actual user HERE on THR has had problems, other than Tony. Sometimes people "heard about" problems but it's just rumor.
If you've had major problems, please post a detailed description of when/what/how and any fix.
If you've used an EOTech in active military or in severe law enforcement usage*, please post your experience good or bad, in addition to voting. (* Severe LE usage = you use one regularly for SWAT or equivalent service, or you have one mounted on a rifle that rides in your patrol car 40+ hours per week and it also gets tested and used regularly even if not on duty; simply being an LE and owning one on a private gun does not qualify as severe usage.)
