We use trackers to keep track of a fleet of small boats on a small private lake, so we know where they are and/or if a guest is lost. This tracker is a great addition to our collections. It is waterproof, which is helpful being on a boat in case it gets splashed. It is very easy to connect - just turn it on, turn on the Find My app on the iPhone, select other item, and it finds it almost instantly. Then you can name the tracker and assign an icon if desired, and you're good to go. These would also work great for luggage, purses, pets, keys, or other things that are easy to lose track of. This works exactly as expected.
