Trijicon makes a newer green dot option on their MRO sight, this is the one I have. Sighted it in, popped in in the safe, six months later....dead.
Tried three new batteries, nothing. I sent off and e mail explaining what happened and the company quickly got me a RMA number.
I had not sent in the warranty paperwork, who does, anyway they repaired it no charge and mailed it back good as new.
Although bummed it died, with a reputation like they have of bullet proof products. Customer service was great and I'm back in business!
