Customer feedback is mixed on functionality, quality, durability, chip recognition and locking. Some customers say the door works well for assigned cats, while others report recognition or locking problems. Noise and counterintuitive setup instructions are also reported concerns. This matters because the door depends on reliable identification and controlled movement, and the display and timer features do not guarantee consistent operation. Ratings are also divided, so they do not establish a uniform experience.
