Ok these are fun to own, wear and use. Does so many things. Instructions could be a little better. Start with the app. They appear to be well made. Enjoy changing the clock face. All functions work well. Blood pressure HB and so much more. Love the step counter.
Tons of value for your modest investment

Excellent product, now you have to wait for its duration, but this great all okey 100% recommended
