Parents are old, do you have a health bracelet for the elderly? What brand should I choose? Ask for recommendation

Most health bracelets on the market now have the functions of sleep monitoring and heart rate monitoring. For the elderly, these are quite convenient to wear on their hands.

As far as the bracelet with the main heart rate monitoring function on the market is concerned, it is definitely hoped that the more accurate the monitored data is, the better it will be worn by the elderly.

In fact, before you asked this question, I started to prepare a Hesvit bracelet for my parents, which not only has the functions of heart rate monitoring and sleep monitoring, but also has the functions of hand epidermis temperature, wrist temperature and wrist humidity, which is quite practical.
