Review on Samsung Galaxy Watch Active (40mm) US Version - GPS Bluetooth Smartwatch with Fitness Tracker and Sleep Analysis in Black by Darryl Montagna

I bought this watch because it is relatively smaller and thinner and also offers heart rate and blood pressure measurement (BP coming later). Also, I love gadgets. I play with the watch a lot, so the battery only lasts 36 hours (I plan to charge it daily). It's thin and fits under the cuff of my shirt. I wear it 24/7 for several days (also to bed, as well as in the shower and to the gym). It's very comfortable (no itching or chafing) and works well. The heart rate tracker is fairly accurate (give it time to adjust to changes in activity) and compares to the heart rate readings I get from gym equipment. I was paying income tax on a Sunday and the watch recognized and notified me that I was under stress and offered to guide me through deep breathing exercises (intelligently). I like that I can set the notifications feature to only show texts on the watch. If it's important, I answer my phone (not my watch). And I like that the notification stops when it detects I'm sleeping (so it doesn't wake me up). The only difficulty I had was this: after setting the clock and updating the software, I had to "reset" the clock to get the alarm to work. The chat/help window on the Samsung website was very helpful. It comes with two straps. The longer strap is encased in a form-fitting case that fits so snugly you won't even notice there's a strap inside. Changing the straps is easy.
