There's been a lot of negs concerning EOTech sights for a while now, but I bought one back in 2007 and it served me well. Last year the reticle started to fade in the left side. I opted, rather than ask for a refund of money to have it serviced. Mine is an NV capable 552.A65. It took about 2 1/2 weeks and it came back to me better than it was new. They took care of me. Despite what I read, I will not trade in my sight because it is the still the fastest sight on target out there, period.
