I had a neighbor set this up for me since he has experience with trail cameras. He said it was as easy to set up as most. We installed it in our woods that abuts his and the pictures it captures are similar in quality to the ones his cameras take.
I can understand it coming without batteries, but it would have been reasonable to include an SD card with the product. We installed the full 12 batteries (vs. the minimum of 4) and after a little under 3 months, have not yet had to replace them.
