Convenient, spacious, and practical.

The device gives full control over feeding the pet. Using the app, I can see if there's anything in the bowl and can always refill it remotely. I can schedule the amount of food for each day of the week. Overall, I highly recommend it — convenient, spacious, and practical.

Both hold 8L. Most hold 5L.

A sealed matte-black reservoir dispensing into stainless basins — weeks of meals per fill, held to the gram, with USB-C and battery backup so the routine survives a power cut. The only decision left is how many bowls.
