Ok - call me STUPID but I went ahead and ordered one of these. :)
Granted I don't honestly expect it to actually DO 1/2 the things it claims (let alone do any of them accurately) however find the device interesting and it currently has a 'impulse buy' price point.
Sadly some/many of these inexpensive Chinese Smart Watch devices can be rather useless without the companion smart phone application which often times comes with a exorbitant monthly 'fee' or 'subscription' for using.
With the Rowatch 6, Rogbid has introduced a new smartwatch that is currently priced at US$34.99 thanks to a discount of above 50%. According to the manufacturer, it offers extensive features including ECG, blood pressure and blood glucose measurement.
