So far, it has worked well. Only had 1 day where it didn't measure sleep time. It has to be on tight to work well. Battery life is great. Looks good and keeps me up on my blood sugar.

Lots of features....bitch to put pins in metal band. No set time directions. Found by accident.

received this watch 14 days ago and becoming fairly accurate is adjusting well to my blood sugar levels and SPo2. the blood pressure e oxygen is accurate I only wish there were more watch faces to select from as the ones provided are kind of lame looking over all this is a great watch.

This product seems to be working well. Set up was easy. I think that the instructions should be expanded to give you more information on the measurements and what they could tell you. They are very explicit that this is not a medical device, however, it can point to areas that might need more attention by your doctor. At this point, very satisfied.

Couldn’t be happier! Tremendous value!
Best invention since the smartphone!
