Aggregate ratings lean positive, with most ratings in the top two star categories, alongside a smaller spread of lower ratings. Without customer comments, the reasons behind those ratings are unknown. The compass's mirror sighting, map scales and low-light markings are relevant to map-based hiking, but the ratings do not establish how well those features work in practice.
