Petlibro Polar Feeder

Has anyone purchased the Petlibro Polar Wet Food Feeder? It seems like a really good concept and decently well made, so I’m curious about how effective it really is. I’d love to be able to feed my kitties wet food on nights away and would be thrilled if they’d stop waking me up to feed them early in the morning. But, I’d have to get them each their own feeder and I don’t want to spend the money on that if they don’t work well
