rule of thumb - for the highest signal/noise ratio, look for reviews that give mediocre, but positive ratings - in the range of 6/10 to 8/10.

What's left is man-made reviews that praise what is praiseworthy, and highlight the real drawbacks the products suffer from
Do not sort by "helpful" in any Amazon property (which is default).
