I haven't been able to verify all of the functions, but of what I use and checked against known fairly accurate equipment, this unit was very close.
Works and wears well. Various display options. Not gaudy teal good purchase.
Been using it a few days now and it's been great so far. Super easy to use and looks good on the wrist.
I have goog experience with this watch.
Being able to check my sugar on the fly is a total game-changer. This watch has been super reliable, and the readings are always spot-on. Honestly, it's just nice not having to overthink it anymore!
