Just received my device after my wife bought it on QVC. I originally wanted it for my dog (Larry), and it worked great for tracking while my neighbor's son took him for walks. It was fun to see the app track his progress around the block, and I was able to change how often it reported his progress. Gave me peace of mind that Larry didn't run off. I also used it on my luggage when I traveled down to San Diego as well, and it was really fun seeing a notification pop up when my bag was being taken off the plane. This device is small and has a ton of different uses. I love that it's rechargeable as well. I would highly recommend this! DP
