Bad app, possibly decent hardware

Do not by this, the app is poorly written and gets worse with each new update. Three times in the last year they have pushed updates that broke the connection with the Health App. Twice they have pushed updates that made the entire thing unusable for days or weeks while they fix the issue. And, their tech support model is to always blame the user or the phone when things do not work after they push an update.
