The verdict

Why it scored a 84

A PCWorld Editors' Choice and still one of the highest-volume 4K dash cams on Amazon, pairing a Sony STARVIS 2 front sensor with GPS, a 3-inch screen and a rear camera for $189.99 list and commonly $125–150 on sale, which is why Value leads at 90. The rear image is softer and overexposed next to the excellent front, the rear cable is proprietary and not detachable, and the front camera cannot be adjusted horizontally. Avoid the A810 Lite, which is not true 4K; Warranty is the softest at 55.
