I'll be honest: I'm always suspicious of things with moving parts, however, these SPIN bowls seems to be robust, and they provide a novel challenge. I also like the versatility and being able to adjust the pieces to vary the complexity. These bowls are suitable for both dogs and cats, although Barney begs to differ!
Here is the official blurb from the manufacturer:
SPIN is an innovative award-winning concept that includes a round base bowl and various interchangeable spinners.
SPIN UFO Maze is an advanced interactive food dispenser. By rotating the disc underneath, food can be gradually released via gravity from the two adjustable openings of the storage cap. The connection between action (rotating the disc), reward (food released per rotation) and challenge (slow feeding area) creates a fun feeding game and exercises your dog's mind.
