These can be really hit and miss, especially many of the claimed 'health measurements'. :)

I've bought a few different models from different OEM's over the last few years and while you should simply forget about 'blood pressure' and 'blood sugar' monitoring via a smart watch (no matter what the OEM claims).

The other more basic features that seemingly all 'fitness' bands/watches have this product will likely do as well.

I'll admit to being suckered into a VERY EXPENSIVE 'smart watch' from a major OEM that required charging every night (so much for monitoring my sleep while the watch was on the charger) and had a mere fraction of the features that the current crop of products have. (it is now a very expensive 'pet rock')

IDK if this (or others) are more or less attractive to wear than what is offered by the major OEM brands but at a mere fraction of the cost, if you willing to take a gamble it might actually work out to be worth it. :)

You just have to take the list of 'abilities' with a grain of salt. :)
