Pretty good, still needs work.
Doesn't do everything advertised. Weather updates rarely work. You must reboot the Sense2 and then synch with the app to get an update. Sleep records are hit or miss. I've had two nights with no data in last ten days. I walk the exact same route every day and get multiple distances. The food part of the app is quite good.Verified purchase: YesCondition: New

I bought this watch because I wanted a watch that would alert me of Afib and had EKG or ECG capabilities. I am disappointed that Afib is not monitored in realtime throughout the day but only at night or in rest periods. Disappointed in lack of easily available, detailed operations and capability information on all smart watches with ECG capabilities.Verified purchase: YesCondition: New

Great smartwatch
Great product. After months of consideration I took the plunge into the smartwatch pool. It was priced right and everything went so smoothly during the transition from the Charge 5 to this. I like the features especially the heart rate ones. It was even easier than I expected. I would definitely recommend the Sense 2.Verified purchase: YesCondition: New

Fantastic product!
Love all the personalization options. Very accurate at counting steps, measuring heart rate, and tracking sleep. Wrist band is slick and comfortable. Clear screen and easy to understand and operate.

Great Way to Replace Sense
Waited to use this since my old, damaged one was still working. Finally got it out and, so far it’s been great. Some nice new features from the original Sense.Verified purchase: YesCondition: New

Worth it
Full disclosure, I have only had this product for a week. So far I love it! I have had a Fitbit before but this one has all the bells and whistles. It measures my steps, my exercise, my heartbeat , and lots of other stuff. My favorite part is that I am wearing Alexa on my wrist now LOL. It also comes with a 6-month free subscription to access exercise routines, recipes, and mindfulness meditations online.Verified purchase: YesCondition: New
