It is very useful, I have two cats and one is on weight watch, this feeder helps me keep her on track and feed them only when they're hungry.
Great feeder so far and pretty indestructible. Our cat is very food motivated (trying everything under the sun to break into the feeder) and has yet to sneak an extra meal. App is very easy to use, as well.
Love it, but the microphone could be louder when pet is called.
My third feeder, first from PETLIBRO and it was so easy to setup compared to previously owned feeders. Very nice design and easy to use phone app as well. I do miss the camera option, 4 stars as a feeder. 5 if it had a camera. “ Food for thought”
