I have 2 Moultries, the basic black model which runs $99 is nothing but junk! It takes a 6 volt battery which usually last about a week, even with a rechargable battery it sucks!
The other Moultrie I have is the 6.0 IR, it takes 6 D batteries which last around 3-4 months but for $300 it's over-priced about $100.
