I purchased this watch in March 2017 and within 4 months it stopped to work as I got a swollen battery. I am trying to contact Bingo support but no one picks up the phone. I sent an complaint to Amazon and they promised to call me back in next 6 hours, on Sept 8. I am yet to get a call. The warranty expires in few days and I have no way to get any support or even a paid battery replacement. Not worth the money I spent.
