Excellent for the price. My 10th field monitor or so. I have a lot and they break a lot. This one does not and the quality is acceptable for focus pulling and even for the director to watch. Ordered another.
I'm using these for studio camera viewfinders, so I needed HD-SDI loop through and tally. Nothing else can touch this price for those features. The larger size is a bonus. My only complaint is the lack of an included power supply, luckily I had some in my inventory.
