Maybe I’m lucky but I have two 512 E O Tech and gave one to my Daughter for her duty rifle. I also have a 511 and fortunately all mine have been gtg. I use Lithium batteries in my 512’s but I’ll admit the N batteries in the 511 don’t last but about 6 months. I can afford the batteries for my 511 and I use it on a 22 LR AR-15.
I always carry spare batteries and have back up iron sights with my E O Tech sights.
