Don't buy a Samsung Smart watch! Less than a year after getting it the heart monitor sensor fell off. Apparently it's a problem a lot of people are having. Now, a week after the one year warranty expired, the watch is completely dead and will not charge. What a waste of money! Samsung's customer service told me that I need to complain to Costco where we bought it. That makes no sense. Samsung needs to stand behind their products. The watch should not fall apart within a year and definitely should not become a paper weight shortly thereafter. Save your money and invest in any other watch but Samsung. So much for my Valentine's Day gift
