How long should a feeder motor last???

[Tex21]

We got 3 of the cabelas photocell motors/spinners and they lasted 10 years before they started acting up.

I have an old 6 volt Moultrie feeder motor with photo cell. Still going after 20 some odd years.

We have several feeder motors on our place that have been spinning for nearly 20 years. Anyone know if Cox feeders out of Livingston are still in business? I'd like to get some new rigs from them.
