I bought one a month ago and put it in the woods. when i switched cards and got home i learned that it took pictures non stop. when I got back to it last week and pulled it out of the woods i found that it worked fine since I first switched the cards, other than it did not take any color photos. All the pictures were taken with the IR lens.I have moved my camera around and found that it works perfectly fine if it is in open sunny areas with low brush, which rules out most spots.
My guess is that some people will have good luck with the camera because their conditions will be right, but most will have issues with this camera.
