Bought 2 SK's to monitor our lot while we build our house.    When you figure the cost of batteries, the SK will more than pay for the difference in short time.   They suggest not using the SK on camera setups where you get tons of pics, like feeders.   Tactacam suggests buying the bigger solar panel for that type setup.  

Tactacam has pretty good support on facebook too.   if you have any issues, "real people" usually reply to FB posts real quick and get you going.
