I bought a Fastfire II in February from an online dealer NIB and it had a bad solder point in the battery compartment that failed immediately. Per Burris' repair procedure I sent it in as an out of box failure on my dime and included delivery confirmation sig (UPS) so I'd have proof of delivery (which I did receive back). That was in February. Still never got it back. Emailed them three times about it since then, including today, and no response. Not happy. Included the warranty form, SN, and delivery confirmation so they know I'm not a scammer. I was going to get a couple of Fastfire IIIs (like that you can pull the battery w/o removing/re-zeroing vs the II model) but now, no thanks. I'll go Trijicon RMR or something else because Trijicon seems to care about standing behind their product and doing warranty work. Just venting a bit, but in a nutshell, Burris sucks at support and they lost a loyal customer.
