    We have three of these. We use them for friendly competition and to keep track of Grand daughters sleep. It has problems with the Android system. The service is done all on line, one e-mail contact per day, and takes 24 hours for a response. They do not respond on weekends, only Monday thru Friday. Help is very frustrating. Recommend with reservations.

    I was a little disappointed when I found out that 2 people couldn't use them. They are only good for 1 person. But I still like it.

    You must have a IPhone latest model or Samsung and then it does not work with the sleep tracking feature.

    I have now gone through 3 wrist bands in less than 4 months, it breaks easily. A leather band is better.

    I wanted a fitness tracker that I could wear in the pool. This tracked steps and sleep a and was allegedly waterproof. I would have been happy wit it but it quit working after 10 days. I returned it and later bough the Garmin HD whitch was much more expensive but works
