A great deal if you can find it at the right price.
While you're stuck at 30Hz at 4K over HDMI, this isn't why I bought the monitor. I was looking for more workspace and looking for something with a Display Port connection. This monitor fits the bill perfectly. At 28", it seems to be perfect for 4K. Colors looks good, and the monitor is very responsive. This was a great find, as I was able to get one for ~$150 used. Even at the new prices, it's well worth the money.
