The wristband sizing tool measures 'snug' to the line between small and large. What size would you recommend?

[Ecm]

I'd suggest the large, if you're on the edge. The device doesn't function well if it's too tight against your wrist. Also, you can get replacement bands for approximately $10 if you choose incorrectly.

I agree with Ecm... and the larger band is able to be adjusted a little smaller, too - in other words, there's some overlap between the larger and smaller bands.
