I purchased 4 for public land use because the value of them I didn't mind getting stolen.. I put 2 of them out before I left for Colorado for Elk hunting and came back and they did 1 24hr cycle and quit so I thought I had a setting wrong .. I replaced those two with the two other and the same thing. I called in and they replaced them and they are working great .. I must have had a bad batch. Muddy always has great customer service ! For the price I recommend them and hope you don't have the same problems I have had.
