Device is good. App is not.
I have no problem with the device itself, but the app is horrible. I am not sure why there are ads-on purchases Maybe it means it doesn’t work until you pay extra. It took Almost 45 minutes to pair. The sometimes it imports data, sometimes not. Also the GUI is awful. There is not even a BP chart to plot your data. Also could not find an interface for Apple Health, and it’s now in the box being returned Question for the company….why would you make a decent device and pair it with amateur software.
