The chipolo work very well. It work either on Apple network or on Google network. It does not work on both at the same time, which I thought it would. I am a bit disappointed. Nevertheless, it is easy to configure and it works well up to now (3 weeks). Mine will be used to track shipment.
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.
