Just got this item delivered today -- so this review doesn't cover any info on the device's longevity, but everything else about it earns it a solid five-star rating from me.
Bought this to use as a screen for a Raspberry Pi setup. Picture quality, sharpness, color, color consistency, and brightness/contrast are all superb! My screen looked a little dim and greenish when I first turned it on, but after making a few changes to the screen's color/brightness/etc. settings with the screen's own controls, it now looks perfect to me.
Audio is good enough, and there's a 3.5mm stereo-out jack in case you'd rather connect it to external speakers or headphones. If they had provided better speakers it's likely that the screen's housing would have to be thicker. I'm glad they used good thin speakers instead of going for excellent thick speakers.
The price point is great at $140, and it's a full-HD screen (1920x1080.) The other major selling point for me was the screen's ability to be powered by USB. I tested it with an in-line USB power monitor and found it consistently drew about 7.3 watts (5.27v @ 1.38amps.) This makes it much more usable than the majority of similar screens I've seen on Amazon. Most of what I've seen takes a 12v/2amp power supply and most resolutions seem to be 1366x768.)
Among many other uses, It's perfect for a portable Raspberry Pi system. A single $30 USB power-bank can drive this monitor, a Raspberry Pi, and reasonable USB peripherals (e.g., keyboard & mouse) for 5+ hours easily. I'm sure you could get 10+ hours with a larger (i.e., $40-$50) power bank and more moderate current pull from the Raspberry Pi.
Again, I can't recommend this screen enough. Very very happy with it!
** EDIT: Be aware that the HDMI inputs are HDMI mini inputs. The HDMI cable that comes with this is regular HDMI <-> mini HDMI, so you'll be able to use that to connect a regular HDMI device to this screen. If you want other/additional cables, just be aware that they'll need to have a HDMI mini male connector in order to connect to this screen.
