About a month ago there was a deal alert on refurb moultrie m80s. I bought one. Cam seemed to work fine for one week then have had issues with no pics stored on cam, as if it was having issues trading card out card was not getting seated properly. Checked cam today and it was dead. I didn't bring spare batteries but am assuming batteries already went dead. Hooking it up to an external will not be an issue but have a feeling it may be more serious. Those cams are supposed to be able to last month's on the 8 double As. Lesson learned I guess.
