I can't begin to say how thrilled I am with this device. From the outside design to the multitude of features, this watch is awesome. I love it with it.

My pops had a medical emergency recently and this watch just help us monitor his health with features that will keep him moving.

Got this for my father in law who’s not the most tech savvy. It was easy to set up. His favourite feature was he could chose a picture as the watch background

I was interested in this watch because it can evaluate the quality of my nights. And, encourage me to move more. There, it does exactly what I expected. It reminds me to move, it counts my steps (which encourages me to do more). It takes blood pressure, pulse, blood oxygen level... I compared it with a chest sphygmomanometer and the blood pressure measured on both devices is very close. So we can consider it reliable. The same is true for the pulse. I did not compare with my oximeter, but the rates taken are comparable to my usual rates.
It can be useful for people who suffer from high blood pressure and therefore have to monitor their parameters regularly.

On the first two weeks of wearing the watch, and I've been getting blood pressure readings that were around 130s. Thought it was a glitch but when I went to see a GP 2 days ago, the doctor's monitor almost matched my watch's results. Doc tested me 3x (maybe she was a bit skeptical too) and even she was amazed at the near-accuracy of this product. I'm in my 40s, don't smoke don't drink and I would not have suspected that my BP's slightly over normal ranges had it not been for this smartwatch. That was a good catch indeed. I also enjoy the other features like tracking my sleep, heart rate, workouts, steps. I receive messages and calls through the watch. I believe you can also send texts and make calls with it but I have yet to explore that function. I also love that I can control my audio with the smartwatch - no more fumbling with my phone when I need to change volumes, skip, rewind, etc. If you are on the fence about getting a high-end smartwatch like me, this one works just as well in my humble opinion. I bought 2 more to gift my family with and they also wear theirs everyday.
