I just checked my I-40 for the first time today after three weeks in the woods. The rechargable batteries were at about 45% when I put it out so I wasn't surprised that it was dead when I checked it. The temps have been in the high 90's+ for much of the time the camera was out. I also had it set to take video in the highest quality for the most time possible. I have video of a few does on a salt lick along with rabbits, squirrels and coons. Overall, I'm happy with the quality of the image. I'm not sure the trigger time is up to advertisements but I'm willing to give it the benefit of the doubt with the temperatures. I'm thinking this camera will do well once it cools down a bit.
