There is no always on display & different watch faces available
30 October 2018
It's a seems like a good smart watch with all essential features such as blood pressure, heart rate and blood glucose monitor. But there are flaws too. There are only 3 watch faces available which looks little childish watch faces and the display is not always on as described. Magnetic straps is okay, you can also use another straps of your choice. Da Fit app works fine for this app. I am returning this watch just because it doesn't have many watch faces (like other Opta watches) and no always on display.
