The supplied evidence contains aggregate ratings but no written customer-feedback summary, so it does not establish what buyers praised or criticised. The rating distribution is mostly in the highest category, with ratings across the lower categories too. Treat that as a broad satisfaction signal, not evidence that the contact or residual-action claims work in a particular home.
