Air chrony quit working today. I have only used it about 10 times since I got it this spring. It was on and recorded 3 shots and then froze so I shut it off and turned it on to a black screen. Nothing. I put in new batteries after checking them with a meter. I messaged Air Chrony who is the seller on ebay from Czech Republic I think through ebay. I hope there is something I can do to get this repaired. Has anyone else had any problems with this chrony? thanks
