i bought 2 of those 3.1 cams off of ebay and both were (pardon the pun) bullet proof. to date they have never malfunctioned and always take good pics. they also are plagued by the ocasional whiteout pics but you can still make out the deer and points. it does have a slow trigger but most cams do. here is a pic off of my 3.1, have fun with it!
