It worked fine dual power meter. control of app and meters. Even had left right battery display. It had everything needed and wanted. The company did an update. Now log into old it tells me make a new account. Go to log into old it says make a new account. I can't get anywhere. I went from 5 star loved it to if possible a 0. don't purchase unless intended to handle issues. I wish it was the product I depended on and loved.

I have four 4iiii precision power meters. The app only lets me register a single one. Then I have to delete it to pair or even see another one in range. So, while I can update and use the power meters the most recent addition, the chipolo tracking, is basically useless because I can't keep all the devices in the app. Just one. Very frustrating.
