How it compares in Radio Communication
Across the 38 rated radio communication products we track, the typical score is 4.4 out of 5. This one sits at 4.6, which puts it in the upper quarter of the category rather than level with it. Where almost everything is rated well, the gap at the top is small in points and large in practice.
It carries 18 ratings against a category median of 356. That is a thin base by the standards of this category, so treat the score as provisional: a handful of extra reviews can still move it either way.
On price it sits in the upper third of a category running from £6.59 to £210, where the midpoint is about £37.02. It is priced above the field and rated above it too, so the premium is at least matched by how buyers rate it.
