Got a gift for my husband in February 2016. No major issues till now, accept once the heart monitor stopped working for like 2 days and I was scared but it started again after a system update. I don't know why it happened.
It's a good watch and I recommend this. My husband is motivated and he even joined a running club and completed 21k this year. :-).
Apart of this , only difficultly I find regarding the cleaning of the watch as I been used while running, we need to clean the sweat else it...

Good for marathon and daily activity tracking

This is the best sports watch one can have.

More than Value for Money. Love it.

Good one....

Good & amazing product,fast delivery.
