What to know before buying

Listing details to confirm

The listed 13-day battery life is an advertised daily-use figure, not a guarantee for every combination of GPS, calls and tracking. The listing also states 2.5 hours charging time in its feature copy but 1.5 hours in its details, and gives conflicting dimensions as 1.97 x 0.79 x 1.97 inches and 10.15"D x 1.85"W x 0.57"H. Confirm the selected listing details before purchase.
