I’ve had this for about 3 months and mine is working great. I got it because we have 3 cats (lazy, lousy mousers) and we’re expecting to be gone for a long period of time. We got the larger size and it’s workng properly. I set it up so we could make sure everything worked before we left. I do find that the food doesn’t last quite a week on setting "2" 3 times/day so the neighbor kids will need to come twice a week to fill up the food bowl.
