I use the Bushnell's. I have some of the older ones and one of the new HD's. It is the trophy cam HD. I like it because they fit in the same lock box. I have a older moultree that got smashed this year from a cow rubbing it on a tree. Cracked the led so it is done when the batteries runs out. So the lock boxes are not only for people but cows, bears and such. I ran a few of my Bushnell all year long around our property. The batteries went out the last week of April after running from May the year before. So it almost went a full year. This was at 9200 feet and some really cold weather.
