i wish that reviews of these fitness gadgets would delve into validating/confirming the accuracy of data presented by the devices.
these machine manufacturers make all sorts of claims about the data they generate and nobody ever tests these claims in a standard and scientific manner.
every "review" is basically a summary of features, never a test of the actual devices performance.
Internet influencers are not really qualified to "test actual device performance". I firmly believe that these companies validate their promises through health authorities to some degree, so the product is not being released until after that process is completed. Of course, is that voluntary, or mandatory? Should definitely be mandatory.
