I have been using Cuddeback for about 2 years now. I am up to 24 cameras with 4 home units. By far, my favorite camera is the G Strobe. My locations have the cameras out year long, so I have added PW3600 to all cameras. I also have added a second battery in the solar for any cameras that have limited sunlight (deep timber, etc).
I have added a mix of daytime/nighttime pics of the Strobe cameras.
The only con that i can express is the lack of ability to aim the cameras, but with patience, you will get the shot you want.
Always keep in mind that if you are getting foggy pictures, it may not be the camera, it may just be the environment.
