This is similar to the 1st feeder motor I bought in the late 70's or 80's (can't remember). I bought new ones from cabelas 2 years ago and none of the 5 I bought are working. I found the old ones on a shelf. Cleaned them and put a new battery in them and. Damn if they aren't working still. I have 2 from then and they are on the job today. How can you beat that? 30 year + motors working today.
