Merging opinions on Amazon can be respectable, and is beneficial for sellers who want to regulate a catalogue of really related products and solutions – this sort of as the very same merchandise but in a various color.
But utilizing these types of opinions for unrelated goods is from Amazon’s conditions and situations, due to the fact it can make something seem additional well known than it is.
Which? focused on just just one group – Bluetooth-enabled headphones – and followed the evaluations for the best 10 goods about the program of a month, from February to March this yr.
Most of the makes ended up not domestic names and were being all sold by much more than 1 vendor, so Which? was not able to identify irrespective of whether the makes by themselves have been implicated in any wrongdoing.
None of the sellers contacted by Which? replied to its requests for comment.
The most hugely-rated item boasted 5 stars, carried an “Amazon’s Selection” stamp of approval and arrived with 40 glowing assessments. But none of the testimonials in fact linked to the headphones them selves – rather they were being for cuddly toys.
