As far as I know because I only run one feeder and have had this one since around 2001 and have not had a need to try another one. Have had a couple issues that were self inflicted and called. You can actually can call and talk to a person that you can understand. This is one of the only reviews I have ever done because I feel they deserve it Check out their warranty. Awesome. Keep up the making of a tough, dependable product.
The feeders I have are at least 20 years old and still work like the day I started using them. All I do is change the battery every August and reset the time. This is the only feeder I use!!!
Thomas, we really appreciate the review. Thank for your support over all these years! How about we make it 20 more. ;)
