The glucose monitor is not functional.  It makes it look like a real reading, but infact it's identical every single day, no matter what I eat, and no matter if I wear it or my husband wears it.

I tested similar Smart Watch E-88 E-86, found them good except BP estimation not precise, the others are good enough. Thank you 💕 so much!

There are a number of smart watches on AliExpress that claim the ability to monitor blood glucose and BP (EKG, etc.) - the one I purchased to play with does perform the functions specified, but they are no where near accurate when compared to devices like the Dexcom G6 or any number of blood pressure cuffs.  I would call these watches a "proof of concept" and "not ready for prime time."

There, I just saved you $50.
