The plusses and minuses - Command Arms Accessories Hartman MH1 Red Dot Reflex Sight

I bought one when they were first released. $600 for a quality red dot was not terrible. After owning it for 5 years, here's what I've learned: The manufacturer, Mikey Hartman, who gave me his personal cell phone number the first time I had an issue not long after I bought the sight, ghosted. He was kind enough to throw in the IR remote control, but I was never able to get it to work. Now, the internal battery loses power very quickly and I've been unsuccessful in getting answers as to how to get it replaced. I can't even find anyone to talk to anymore. While the sight, when functioning, is an incredible one, it appears they will all end up in the garbage.
