Summary: The ONE 3rd Edition adds an excellent safety feature to an already outstanding unit, though it's a shame battery life hasn't been improved. Regardless, it's definitely great value at this price.
Pros: Design and aesthetics, user interface, excellent maps, "Help Me" safety feature, fixed speed camera alerts
Summary: Right from the off, the ONE seems like a good deal. TomTom has proven its capability time and time again over the last few years, and this new, 3rd Edition release of the ONE has all the benefits of that experience.
