I made my own cages, not that hard. I have never had the battery die because of the dust. My oldest one I bought in 2003, have had to replace the motor 2 years ago and the panel at the same time. I used a standalone panel, now place on the side of the barrel.
I have a couple friends with some that are over 15 years old with minor maintenance. I really like them for their reliability, especially for less than $100 shipped.
Also use the dikes when needed. Cage helps me more for squirrels.
