What about Amazon own brand products? I find it unbelievable with their own reviews and ratings. For example, a Fire HD 8 tablet have almost 120k reviews with 4.6/5 stars. It doesn't make any sense. These tablets are junk quality with crappy software.
I find Costco product reviews are way more trustworthy. Even though they're 3-star, I still buy them sometimes.
Many get the Fire tablets because they wanted a cheap way to access Kindle on a color screen. Even more love it because there are dirt cheap options to hand their kids. At 1/6 the price of a base iPad Mini it can even arrive DoA and be rated well since Amazon will just RAM without asking questions. People aren't always looking for solid metal frames with high quality software, many are happy to find the cheap piece of plastic that lets them watch a movie in the car and will give good ratings to the product that let them do that for the price of eating out for a night.
I think maybe there's a conflation of ratings and usability of some people.
As for other places it has a 4.5 or higher at every place I see on Google shopping including target and best buy.
You wouldn't rate a McDonald's a 1 star because it was shit compared to the steakhouse down the street you'd rate it based on how it performed against similar competition.
