Cat Mate C500 - Auto Cat Feeder

Got these for my two cats. Seems straightforward enough to operate. Easy to clean. Even has ice packs (not featured in video as they were in my fridge). At 8pm tonight the two cats seemed to respond, although Pixel needed a push. Neon seems to have got the idea.
It has five bays, so the open one I filled with dry food. The other four bays I will fill with wet food (ice packs will be installed underneath). I set two times (9am and 6pm) and so this will feed the animal at those times for 2 days. I could have set four times but then all four feeds would occur within one day. If you set one time, it will feed once per day, not recommended for wet food but dry food would be ideal. Wet food may go off, so keep an eye out for this, especially in warmer weather.
These were £40 each (2020 prices) online, and came within 2 or so days. They say Alkaline batteries last a year. Perhaps they might but I'm using cheaper ones for now as that is what I had.
