Aggregate ratings are mixed, with a majority of ratings in the five-star category but a substantial spread across lower star levels. The ratings alone do not show why customers felt this way. For buyers, fit and compatibility are particularly important because this product adds length to a regular 49mm Ocean Band rather than replacing it.
