Absolutely rubbish! Only giving it one star because there isn't an option to give it zero. I tried to update my fitbit versa for the fifth time. I had it on charge near my phone for 14 hours and that isn't an exaggeration. It is still telling me that an update is available. I can't change clock faces or do anything else on it until it has been updated. Don't bother downloading or buying a Fitbit. They're utter crud!
