When I said old feeder I was referring to the 75D model of about 5 years ago. It has a solar charger that is about 1 foot long. That one is a champ. At least 5 years of trouble free service. The reference to new feeders is to 75D units purchased in the last 2 years.

Thanks Ron I will call. If this works I will be one happy customer.

I also have a 25D hanging feeder that is 5+ years old and it also works great.
