Case in point, I bought a power bank the other day, it was freshly posted and had 2 replies. I didn't post in it so received no notifications. I saw the thread again today and it was in negative score, so I started reading. I realized that the brand wasn't reliable and I should just spend a bit more elsewhere, well that's important to me as I have a much older power bank and it still works flawlessly, so I cancelled my Amazon order.
If the score wasn't there, I might have just skipped the thread, assumed that power banks are power banks and they're all reliable like the one I already have.
