I can do 3 cuff readings within 5 minutes are easily get +- 10 for each measurement. So it doesn't have to be super precise to have comparable accuracy to a cuff. Also the fact it is making continuous readings (even while asleep) is very helpful.
By "cuff" you mean the brachial artery ones, right? I'd be interested in both accuracy (same value when measuring the same thing) and precision (how close to actual value).

Yes, the one that goes on your bicep.
Anecodtally, it seems to be within the variance of the cuff (plus or minus 10).
Trying to measure both at the same time is tricky as you can't actually tell the Hilo device when to make a measurement. It does it on it's own scedule.
You are supposed to calibrate the bracelet against a cuff at least once a month.
