Review on Renewed Garmin HRM-Swim Heart Rate Monitor for Accurate Water-Proof Tracking by Devin Girard

Works very well and accurately. I use it almost every day for at least 1 hour. So far there have been no problems. Easy to connect to the phone (I use Samsung S9 Plus). It works great with Samsung Health. You have to choose what exercises to do when you start. Then you see HR. Otherwise, there are other apps that only allow you to see HR. It comes with S, M and XL straps. At first I needed XL, and after losing weight I needed L. Just connected the S and M straps and made it longer, like L. Now I only use M. The strap doesn't slip off. and comfortable. Sometimes I forget it after a workout and it stays there longer. I hardly notice. I am happy with the purchase. and I recommend it.
