Bests & Worsts Reviews from Amazon

love this. I bought this to use on my dog. I plan on a trip. there will b a lot of dogs. the Cube is great. Use your phone Cube app (easy) push, the Cube lights up and beeps, you can hear where she is. You can also see on your phone where the Cube is. In the even that you can not find your phone, use the Cube to find the phone. There is a button on the Cube, push it, the phone will make a horrible beeping sound. Note: I only use the Cube on my dog's harness, not on her collar, she's too small, and I only have her where it when she's working. She's a Svc dog. Thank God for her ;) Hope this helps you. Use the Cube on your keys.
