My current Cuddling system has been deployed two years this weekend. The G-series camera has not been touched in two years. It is mounted on a tower stand with a PWS-3600 solar unit. Four J-series cameras (all with PWS-3600 solar units) are operating with minimal issues (ants, particularly seem attracted to Cuddebacks). All four J-Cameras purchased in January 2020 are still working well. For the first two years they operated an a link to the house system, not a cell system. Battery life was the big issue with my early AA versions. Since adding solar, battery life has not been a concern. Last year I added an L-series black flash. Today I added a PWS-3600 solar unit to that camera.
If someone would have said ten years ago (when I started using the Moultrie Mobile two-piece cell system), "hey, here is a camera that you can deploy and not touch for two years" I would have thought "no way." I am happy to post this positive report.
