While five hours' talk time was rather poor, albeit adequate for most users, the benefit was easy to see, with the unit weighing only 10 grammes. Not surprisingly, once in place it was scarcely noticeable, and despite its short reach, the mike returned quite a reasonable performance when faced with road noise. However, the unit only managed voice tags when stationary. With a handy cord and soft pouch, it was well priced and is worth a look.
