I bought my pulse values in different situations to monitor my device and allow recording. The Heart Rate Monitor works very well and reliably. The battery life of 36 hours may be relatively short for some, since I anyway daily to the laptop close the device to read the reports and save, it's perfectly fine. Pedometer is unlike some other devices very precisely. The app works unfortunately also on the LG G2 incorrect reliable. In pulse display between interrupts again the Bluetooth connection (device remains coupled), but since all data is stored on the device, you have no loss of data. The alarm by vibration is very comfortable and reliable. A very successful device to update the app. The software for the PC is very good.
