Anyone having Problems with these feeders??. I just bought two from Greg...one doesn't work as the discharge wheel won't spin....I agree with some of the other posts about wire holes need to be sealed and bottom will have to be watched...things I can do but shouldn't have to...But while I don't mind paying for a good product...I don't appreciate having to spend my valuable time fixing and shipping back and waiting on parts etc..not to mention no one to call on weekends when you need to troubleshoot....Sounds like these units need a quality control update at the plant..
