Cats steal easily if they want
The surefeed is good that It most often leta just the programmed chip/cat eat. But it is so easy for the cats to reach on the side and to sneak next to to the one who it is for. To this expensive product lost most of its use.
If the makers would have made the side walls larger that could have fixed some of the stealing. Also; the lid closes late after the cat walked away = lot of time to steal food for the other cats.
I am a bit disappointed. Sorry to say.
