Most people sent them back to the manufacturer and received a refund of full MSRP. That ship has long sailed but it definitely affected the trust and pricing of the ones that weren't returned- especially one 12 years old.
I have a 2008 I will sell for $200. Disclaimer: It is in the dreaded, "fade phase, nitrogen leak", and no longer visible in daylight. Just FYI; EoTech no longer supports repair on them either.
Nothing imho.. I had safe queen 2011 model that recently failed miserably while sitting on top of a 9mm pcc.... Eotech said that they won’t repair it even on my expense.
