## Customer feedback

The supplied aggregate ratings are strongly positive, with nearly all recorded ratings in the top two star categories, but the sample is small and no written customer feedback is provided. These figures do not establish temperature accuracy, heating performance or suitability for a particular tank, so use the listed capacity and operating details when deciding.
