D'llesell Professional Health Monitoring Smart Watch G08 - Medical Grade ECG, Blood Pressure, Blood Oxygen, Heart Rate Monitor - Sports Health Watch (Brown)

I like this watch most, features work as expected. Blood pressure mode seems to work in that it measures throughout the day and records changes in pressure . Temp function is good. Reminders are useful yet the sleep function is not so good, it mostly does not work. I've had to restart it several times to make it function. in all not too shabby. the postage is expensive above what is a quite expensive watch. looks well made and the wristband is fairly comfortable to wear. battery life not too good but i do check it often and test features regularly. I do have another watch half the price of this one an d I'm not so sure this is really worth the extra cost. I've wearing it for over a month now and i am very happy with it. build quality is excellent and its not heavy to wear, in fact it's very comfortable and the strap does not make your wrist sweat. my routine is to charge it while I wash/shave each morning to keep it topped up which is perfectly fine. After using it for a few week's I've managed to work out how the sleep function. it records your LAST sleep period so if you've woken up during the night for several minutes got out of bed for instance, it calls this an end of sleep and when you go back to bed.it begins a new sleep period and this is reflected in the morning as your last sleep period which is very accurate. I did contact the seller who replied by return, suggesting I reset the watch, wrong answer, but delivered very quickly.
