Ive spent hundreds on cheaper products and none come close to LandAirSea 54 with ShareSpot (TM) location sharing. I purchased this to keep track of my teenage son. You able to access via desktop and phone app, simultaneously. Also, ShareSpot is an awesome feature, that shouldn't be overlooked. I sent my husband a link and we were both able to keep tabs his activities. Magnet is super strong and and you can activate "dark mode" so that it cant be seen by anyone. It uses Google Maps with the ability to "Browse Street Images", (you can drag the little man onto the map for detailed building and street view). Pretty powerful stuff!
