Reviews in general are not a great indicator because the average person writes a terrible review. Either the review is made based on irrelevant details or they lack the perspective necessary to review the item appropriately.<p>Two recent examples:<p>There is a cheesesteak restaurant near me that has 4 stars on Yelp. People rave about how they have the best cheesesteaks ever! Yet if you look more closely, reviews from people that have eaten a cheesesteak on the east coast are much lower. After trying it myself, the food is terribly bland.<p>I was recently looking at coffee makers. The &quot;Ninja&quot; coffee maker has glowing reviews (though I suspect a chunk of them are fake). But the reviewers are comparing this $200 Ninja machine to their $30 Mr. Coffee. Again people that actually like good coffee are rating it much lower. Then looking at the reviews for a different coffee maker, many reviewers are comparing the result to their Aeropress or lower end Espresso machines.
