We have been very pleased with our Chipolo One Points. We have taken a few trips, on airlines and cruises, and they have worked perfectly. It's so reassuring to know that your bags have been loaded or unloaded and not wondering if they've made made it to your destination with you. I keep one in my C- Pap bag and backpack as well, in case we are ever separated. I don't leave home, on a trip, without it. 😊
