## Customer feedback

Aggregate ratings lean positive, with most in the four- or five-star categories, but a smaller one-star share makes the overall picture less uniform. Without review comments, the reasons for either reaction are unknown. For a standalone alarm with an LCD and replaceable batteries, these ratings do not establish alert performance, battery life or suitability for a particular installation.
