Anybody Have Experience With Samsung Odyssey Monitors?

Are they as good as they're marketed? Do they last long or they die quickly? What problems did you encounter? How is Samsung's customer service and RMA process like? I'm considering to get the Odyssey G4, but for a FHD monitor it's kind of expensive. I can get a QHD monitor from other companies or even the Odyssey G5 for slightly more. Apparently, the G4 has been reduced by over 100 dollars during major sales on Amazon like Prime Week and Black Friday-Cyber Monday (instead of usual 50 dollars discount).
