Mervin Cummings I had a bit of a problem when trying to pair it up with my bluetooth after it connected everything is working perfectly. There are no instructions for it so you have to figure it out as you go. So far so good. It keeps track of my heart rate sleep stress so im liking it so far.

Stanton Pollich Perfect, ring arrival before the estimated date.
First test of the number of steps, very precise 49 not carried out the ring indicates 50.
Saturation rate 98%, my device gives exactly the same value and so is the heart rate.
It is also very simple to clear the telephone ring with Qring app.
Thank you for all this for an uncompetitive price
