This remote locator has been a life safer. My husband and I share a vehicle and we only have one set of keys. We also have different ideas of how to handle where to put the keys after we have used them. This device has solved many, many arguments and saved us considerable amounts of time in trying to find the keys. It has been a true lifesaver. We have also been able to attach the other ones to some other items that we frequently can't find. This has included various different items and has made finding things so much easier and quicker.
