Bought this for when we are away for vacation so I haven't use it long enough to see what pro and cons about it. I tested it to make sure it works. Setup is pretty easy. To bypass the scheduled feeding, you need to unlock it first, then press the Manual button (one time for one portion, etc).I made mistake by putting the feeder where ants could reach it, and I found some ants went up the main storage. I still need to figure out to solve this problem.Cat seems interested with this feeder, which a good sign because I got it a fountain water bowl and it wouldn't even come close to it.The recorded voice is pretty loud. Unless this feeder is far away from you, do not schedule it on your sleep time.
