I have two of them. The batteries go for and 3-4 months at 700-800 pictures a week for me. I made sure and pointed mine low an the ground under the feeder, it took a lot more picture that way. I am about 25 and 30 feet away from the feeder, a bit further away would give a wider picture, I just haven't tried it.
PaulZ2 is right on the love them-hate them part. I am no Wildgame advocate, but all 8 of mine work great. I had a $49 Wildgame camera poop out at 3 years old, I could not complain. I know guys that by a new $200-$300 camera every few years and brag about the reliability.
