I bought this to keep track of my heart rate and as an aside to monitor my speed while kitesurfing. This device has an onboard GPS and is water proof do it allowed me to do all that. Now that my long term stress test is over, I no longer need it.

It is in great shape although I managed to put some very minor scratches on lense ( I tried to show those in pictures but they are so minute they are hard to see by picture).

I really liked this device, particularly (and surprisingly) the sleep logging.

HR monitor was very accurate (compared it briefly at Dr office and it was spot on).
