I have mine, and I love it, unfortunately I've been very unlucky, 3 months of trying to get hold of one after hearing they were actually available, and then I had a stuck pixel and 3 half ones show up on day 1 /cries . Waiting to hear what's going to happen with it exactly between Asus and Overclockers on Monday hopefully.
It's really lovely otherwise, 240hz was enough to make me happy really as nothing I play runs with a high enough frame rate to need more on my old gtx 1060 currently, far less ghosting than my old XL2411Z. ELMB sync worked with everything, freesync worked well no flickering.
Hoping to post back as a fully happy owner soon.
