we run a couple of them and so far they have worked and we have not had any issues with them. we got 3500 pics in 2 months over a salt hole last year with one. the only thing i have against it is that when it takes the pic it makes loud clicking noise and almost every deer we got a pic of was looking right at it cause they knew something was there. you could tell by some pics that the deer were spooked by the cam. but they kept coming back so it must not have scared them too bad. i killed one buck that we had on that cam.
