Had this for about couple of weeks and it has been amazing. I had the frontier S3 and it still worked like a gem but sadly my S24+ phone couldn't connect to it and so I traded it in for a great deal and got excellent upgrade.
I updated from a Galaxy 5 and love how much thinner this watch is and also seems more accurate on blood oxygen levels. Also a serious note this watch alerted me that I had a AFIB. Went to my cardiologist and he made me wear a monitor for a week and yes confirmed AFIB. My 5 never alerted but again maybe wasn't happening then. Bad thing is the battery doesn't last as long as the 5 but thats not a deal breaker.
I love this watch!! The look and performance are wonderful!! I really love how it pairs to my phone and tablet and I can receive snapchats, emails, calls, and texts!!
I love how stylish it looks and have found to my fitness must have, my T.V., Cell, Tablet, watch are Samsung and I have been very satisfied by this brand, I am older and getting back into shape and like how I can monitor my heart and like that it can alert me of an elevated heart rate and it seems to be accurate, very happy with this purchase!
