Aggregate customer ratings are mostly five-star, with a smaller spread across lower ratings. Without accompanying review comments, the figures do not reveal what customers liked or disliked. They cannot establish how well the cleaner handles deposits or fits a particular aquarium, so pane thickness and the listed glass-only recommendation remain the useful buying checks.
