    I love my new watch, I am replacing a Sense 1. The pricing was great compared to many others and I have it already charged, synced to my phone, and wearing it.

    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.

    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.

    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.

    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.
