I have a few of them...I got the "SD ERROR" message after not too long. i called them and they tell you to format your card...we'll, my card was formatted. Ended up sending it back to them and the customer service was great- they sent me a new one. Anyway, I'm mixed on the truth cams but the customer service is superior. I'd probably not get another primos cam. I'd recc any camera that takes AA batteries vs D or C batteries.
