Depends how you use it , and how you look at it I guess.

I use it to get pics of deer I may not have even known existed , and to see what survived after the season is over. I get enjoyment from the pics. As far as a scouting tool for mature bucks? I personally don't think it's a very good scouting tool for mature deer. I had a neighbor glassing a field for me every evening , watching a nice 10 pt come out every evening. When he told me the route the buck was taking I setup my cam and got one pic of him , after that he never used that route again.
