What to know before buying

Listing details to confirm

Listing details conflict: the title and feature text say 1.43 inches, while the technical details list 1.87 inches. Battery capacity is listed as both 400 and 600 milliamp_hours, and GPS is described as smartphone-based despite promotional copy mentioning GPS and offline maps. The compass in the title is not clearly confirmed in the technical details. Clarify these specifications and the claimed 30-meter resistance before relying on them.

The available aggregate ratings are positive overall but come from a very small sample, with ratings spanning five-star and three-star categories. They do not explain what customers liked or disliked, so they offer limited guidance on calling, tracking, battery life, or the listing's conflicting specifications.
