So the PetNet Automatic feeder has been great for my two cats! it is Wi-Fi connected and is wall powered, if the Wi-Fi or power shuts off the feeder holds a charge and still holds last known time to keep feeding schedule. It now supports both Apple and android phones. Haven't had many issue besides the angle on the food bowl doesn't have a good enough slope to drown some foods all the way down to the bottom of the bowl, but its not a big deal once the cats eat the food the rest slides down soo not that huge of a deal. Overall Great product and would recommend it to anyone!
