Aggregate ratings lean positive, with a smaller two-star share, but the limited rating sample and lack of review comments do not establish what customers liked or disliked. Treat the ratings as a weak signal rather than evidence of algae-control performance or suitability for a particular spa. Match the listed 400 to 1,000-gallon capacity and account for the stated variability in treatment duration.
