I am an IT consultant so my schedule is sporadic and I want to make sure my dog was being fed at the same times everyday. As advertised this product seemed to be the answer.  After programming the feeding schedule it worked for 1 day. Up early the next working til noon I checked the feeder and breakfast was blinking. Believe me, my dog will let me know when she has missed a meal. So I tried resetting but had to turn it off and back on to reset the time but the feeding schedule was retained. This product never worked as advertised. I will be returning to get my money back.
