Well ok, this is indeed a totally legit and righteous way of thinking and who doesn't agree with that. But..... first of all you have return policies covering 101% of your expenses. Second you've probably noticed that people tend to be kind of weird sometimes right? Especially in the internet. It's not exactly the place where the absolute truth and evidence happens, isn't it?
Flipping the coin upside down what I've seen are people who changed 6 monitors _in a row_ for blb or whatever else, asking for 5 rma and a final refund. And then if you look at the picture they posted the only thing you can possible wonder if they are totally nuts or just nuts. Probably they just wanted to be that guy who posted his experience of rma'ing 6 monitors for horrible blb and be worshipped by the "oh look what an unbelievable story" crowd on reddit. What a lovely day! LoL
Yet, if you own one of these screens and you have some very slightly blb in one corner, and you set brightness at 100% and take a pic with your 2 Mpixel smartphone, maybe with some incident light from your wide open window at noon, you'll see Hitler himself in that corner.
Don't forget another simple fact, the monitors that are sent back aren't disintegrated by some kind of magic gun of oblivion. They stay in the damn ring and will be picked up by someone else.
TL;DR: always remember people are strange. Don't be that people first, post later.
