I've have a Cuddeback Excite. Have about 3 thousand pics since Jan '07. Was going through batteries about a set a week.
Live in Canada, so its cold. Went to rechargables. Wanted to get another camera this fall. I read all the talk about Moultrie. Bought a I-40 @ Walmart for $140. After 1 week, 2 pics. Beautiful tree!! Moved it to same tree as Excite. Result: Cuddeback= 15 pics ( 12 deer, 2 'yotes, 1 fisher) Moultie= 4 pics ( 1 deer, 3 nice trees). I always take a pic before removing cards to get a time frame of when I'm there and when the critters are. I check my cameras by walking up beside them, sticking my hand in front in a fist form, that's zero, then count to 5 using fingers. The cuddeback will get a fist or first finger, even at battery level of 1. (4 being full strength). The Moultrie was getting fourth or fifth finger @ 80% battery. I gave it a 2 week trial then returned it!! I guess I'll stick with Cuddeback. A little more $$, but well worth it.
