In Manhattan, satellite tracking remained strong until we hit the lower downtown region, but we expected as much due to the narrow sky view. Out on Long Island, signal strength remained strong in all but the most heavily wooded areas. Thankfully, the receiver managed to regain a 3D fix quickly whenever the reception was lost or became too weak.
The Otsia maps were clear and easy to read, and our location on the map was correct. Voice and text driving directions were accurate too, although we would have liked more advanced notice of upcoming maneuvers. As a pedestrian GPS device, the EZ Road did a fine job of finding nearby police stations, museums, transportation centers, and hospitals, but we were disappointed that it lacked a restaurant search.
The EZ Road's lithium-ion battery lasted for 4.5 hours before running out of juice, which means you'll have to plan your walking tours accordingly. If you're looking for a portable GPS with extended battery life, you may want to consider the Garmin Quest, but you won't have the luxury of SD card storage for your maps.
