I really like the watch and how it works, and how it tracks heart rate, VO2 max, and pulse ox. Sometimes the heart rate measures are a bit off, becuase it takes a while for them to "catch up" when there is a spike in heart rate. Also the hydration tracking app has a lot of glitches.
Ok, so I'm not a super techy person and I bought this at my super techy husband's recommendation.
I absolutely love this watch!
I love to see how well I slept (or not), the steps and stairs I take in a day, water consumed, cals burned for specific exercises, HR zones, calendar events, texts, messenger and I can control my Spotify playlist!, the list goes on.....
I highly recommend this watch for anyone really.
