great price, but monitor seems to get relatively poor reviews for image quality, even for a TN panel.

EDIT: after reading a few more reviews, it doesn't seem so bad after all. If only I didn't have a bloody geforce and needed gsync :'(

32% off doesn't seem that good. I await january sales

Heat, as this is a cheap monitor for gamers, but yes, from the review it doesnt sound so good for normal use. I would try and find other reviews though, the guy might have received a defective model.

EDIT

Other reviews dont agree though, with one saying this is caused by an AMD driver bug, and that there are work-arounds.

Tomshardware seemed to think it was a pretty good monitor.

The reviews are mixed on this monitor because Amazon have displayed reviews of this monitor and a 4k ips monitor on the same page.

"Size: 27 inchStyle: Ultra HD"

Agreed there, it'd be a tiny change for nvidia to support freesync but they won't do it so long as their add-in card to support g-sync (which iirc costs like £200 per monitor) still makes them money.
