On the ranch we hunt there are about 5 of them out, I have two of them and I have never had any problems with mine but two of the other ones have had to be sent back and replaced (wouldn't flash at night). I think they are either hit or miss with that b/cI know one of those were purchased at the same time and place I bought mine (webought them together)but if you get a good one you will be happy with it, like I said I can't complain about either one of mine they have bothbeen awesome!!!! I would also recommend that if you could afford $200 go for a I-40, that camera has really impressed me......
