I have three Stren-ADF 75 that I bought from Greg Grimes four years ago. I only have a clogging problem when the GFC gets damp.
Recently one feeder "malfunctioned" and was throwing the food only 5-8 feet. I charged the battery but had the problem. Next I tried a brand new battery. That solved the problem.
Batteries wont last forever - especially left outside in freezing weather.
