I’m not sure if this is just me, but it drives me nuts when I see someone answer a question (for example in the questions section on an amazon product page) to just say that they don’t know or they give an unrelated answer.
For example:
Q: Do these headphones support bluetooth and wired connections?
A: I’m not sure, but my grandson loves these!
The same goes for posts which ask a question on other sites or reviews complaining about a product, despite it doing exactly as advertised. Idk, maybe I should have posted this on unpopular opinion.
Also included in this are reviews on things that are not the product - I remember seeing one that was like “great product, but I’m giving it one star because it was delivered late and the delivery driver was rude” - and reviews based on the buyer’s own failings, like “I didn’t read the assembly instructions and put it together wrong, and then it didn’t work properly, so I’m giving it a negative review”.
