I have one.
Can't really recommend it sadly, build quality, features, etc. is decent, colour quality and sharpness for a TN is really good however there seems to be some issues with the internal power saving system that can't be fully fixed (turning the monitor volume to 0 helps a bit) which causes random flickering and occasionally for the whole panel to timeout and disappear from the OS til you reboot (haven't actually had it happen for awhile). Its struggles with fast white to black pixel transitions, has fairly high input lag (seems to be some issue with the scaler) and overdrive artefacts are up there with some of the worst I've seen.
It has its uses as a general desktop monitor but I couldn't do anything other than slower/casual gaming on it much personally.
Most of the issues could probably be fixed with a firmware update but that almost never happens with monitors.
