I got this bracelet from my dad while he was in the middle of a phone call, during which he was apparently so disgusted by the existence of the thing that he couldn't wait until later to explain instead of just shoving it into my hands.
My dad is diabetic. A friend of his gifted it to him to measure his blood sugar levels, which isn't even a function it claims to have. He apparently also wasn't satisfied with what it does measure (sleep statistics, heart rate, steps taken, calories burned) but I, personally, haven't noticed any problems there.
Apparently, the market price for this was 80 dollars. I have no way to verify this, because literally nothing on the bracelet gives any indication as to who manufactured it.
If anything about this description sounds enticing, I'd say it's a steal.
Comes with the box and manual as well.
