It is the I-590. It is the first cam I have ever bought. I think it takes great day and night pictures. I haven't found that the flash scares the deer at all. The batteries don't last too long once the temps start to fall around the freezing point. Early season, I was getting 300-400 pictures without any battery problems. Come end of October and November, I was only getting 100-150 before battery would start to die.
