A reliable entry-level smart feeder for small and medium dogs, with app scheduling, dual power and a quiet motor at a budget price. A sensible first feeder, though capacity and build suit smaller dogs rather than big breeds.

Common questions
Is the Oneisall good for a first automatic feeder?
Yes, it is a sensible entry-level choice with app scheduling, dual power and quiet operation at a low price, suiting small and medium dogs and owners new to smart feeders.
Will it suit a large dog?
Its 3-4L capacity and lighter build are better for small and medium dogs. Large breeds need more capacity and a tougher unit like the Molly & Cody.
