The best feeder I have experienced is On-Time. No digital anything, sealed great for the weather. To set times all you need to do is place a clip on the rotating time disc. Runs on 11 double A batteries. Awesome rig and I have had them for years. If one were to break, mail it in and they will fix it for you for the cost of shipping.
