Looks fine at first then reality catches up.

Purchased to keep eye on blood pressure, pulse and especially sleep monitoring. While the 'on demand' blood pressure and pulse are often reasonable, sometimes they are not. Repeat BP within a fdw minutes showed wild variation while this morning the pulse history told me my pulse of 67 which was consistent overnight did not change when I got up, made breakfast, went out to feed ducks hens etc. If only I was that fit. Last night had very disturbed sleep, got up several times but was told I had slept well, did not get up at all. Couple of nights ago woke up in morning feeling really tired yet was informed I had just had a great night sleep. Wrong. And the style of watch face choice is poor. As always the information provided does help a new tracker user. Beware the refitting of strap after usb charging....
Would not recommend. Likely to return? High.
