Excellent for the price and arrived ahead of time.

Well, it's a shame it was too big for me.

So far i am liking this smart ring. The fit is good (though i probably should've gone with a size smaller), but still fits great. Aside from the usual metrics like heart rate and steps, it also has an oximeter as well as a detailed sleep monitoring system(movement, light/deep sleep, rem sleep, etc. ), which has helped quite a bit already.

Item as described of good quality

Better than i expected. It seems to be very accurate and has kept track of activity levels, sleep., heart rate and stress level. Quality seems excellent especially given the price point. I'm very pleased.
