I have a Garmin vivosmart 3. I wrongly thought the rolls Royce..... How wrong can you be.1 it won't sync by itself.2 you can't read the screen out doors.3 battery lasts about 48 hours before it needs recharging.4 steps and distance out and back differ.5 Sleep measure is completely inaccurate.Overall summary, NEVER BUY THIS. MY HUAWEI PHONE IS BETTERI have a Garmin golf watch that is also very disappointing. This company is peddling garbage resting on its name from the past.
