I got the (in)famous PG278Q from a local store. For about 2.5 years it worked fine, then it started having problems. I returned it and it was sent in service, as it was still covered by the 3 years warranty. After 2 weeks I got a replacement. Please note that I took great care of my original monitor and I returned it in top notch condition and well clean.The replacement I got was a USED monitor, dirty and covered with glue in some places along the edge (including some hair samples). The monitor screen was clumsily cleaned and there was some white residue left all over it. When asked about it, the store I got it from told me that ASUS wasn't compelled by law to replace my defective monitor with a brand new one. I contacted ASUS and after going back and forth the conclusion was that the customer support team can only escalate the issue, not actually solve it and I should deal with the store I got it from.Really ASUS? You replace a high end monitor with a crappy used monitor that you dug up from a forgotten storage unit? And what about the QC of your products?The story continues with the local store and I won't bother you with the details, suffice to say I had to contact the Bureau of Consumer Protection from my country to get my money back.
