Very nice looking watch, every part of it is high quality materials, very good screen contrast and colors. Measures both heart rate and blood oxygen (has separate LEDs). Arrived discharged, I put it directly to charge with the magnetic connector, very easy. It fully charges in less than an hour and after 1.5 days including playing with it and learning how to use it had still 60% battery. I expect it can last for about 4 days of normal use, probably less if using the internal GPS for outdoor cycling/tracking etc. The good thing is it charges quite fast so I'm not worried. Apple watch for ex. does not last more than 1 day due to many functions, including phone function that I don't need in the watch. Overall very happy, now deciding who in the family will keep it :)
