text: Perfect for keys and larger items. It can be heard from far away, even in a toy storage bin within the toy cabinet! Not at all cumbersome for keys that are often deep in the bottom of the bag or carried throughout the house by our toddler. Like that it comes with adhesive or key ring to attach each tracker and only one remote to use for 4 different trackers so you don’t have to decide which is the most important item to track for the same price as one or two trackers
