I just bought 4 Chili’s, 2 for myself and 2 for my partner. The set up was fast and simple. I now have 1for my suitcase and one for my keys. He has basically done the same.
We gave this 4-pack to our daughter and family for Christmas. Don't know yet what they find about it but they were enthusiastic about it. I know I'm satisfied with Chipolo and I'm sure they will be too.
Bought for an older friend who kept losing keys, to allow more sets to be covered. In the year since his first set, they've found various bunches of keys around 30 times. Previously he had to turn the house upside down only to find he'd left them when visiting someone.
I've been using Chipolo devices for years. The current generation is excellent. I like that it works with Android & iPhone, because I'm an Android user and my relatives that keep loosing stuff (key, wallet, backpack, etc) are Apple iPhone users. It's important that I can have my relatives use the share option so I can help them when they get confused by technology.
