Currently using these connected to my Mac Pro and they are great displays but selling due to travel plans (moving to a Macbook Pro).
They've still got over a year of warranty left and haven't missed a beat, they have a very good anti-glare coating which has been great for me as I have windows right beside my desk and behind me. They have a thin bezel which makes them ideal for multi-monitor setups and are height adjustable unlike many of the cheaper models doing the rounds right now.
Can post pictures if needed but they're monitors so not really much to see, they were setup and haven't moved since so have no signs of usage/wear and no dead/bright pixels that I could spot using pixel tests.
Currently sell for $700 at PBTech -https://www.pbtech.co.nz/product/MONDEL2715/Dell-U2715H-UltraSharp-27-QHD-Monitor-IPS-In-Plane
Looking for $450 each or $1200 for all three, buyer can collect from Darfield or can meet in Christchurch area. I don't have the original boxes so afraid I can't courier them.
