Summary: At first I thought it didn't work, but then realized it's not Plug-and-play on OSX. As soon as I added the driver, however, up came the screen. I haven't really found an application for this yet, other than keeping a little email alert window off on the side, but that's a software issue. From a hardware POV, this device does what they promise, for a pretty good price.
A decent little portable second screen. Mac users beware, not working on mavericks. Paid touch drivers!

Summary: Was great until Mavericks. Display port hasn't released a good driver for the updated OS so now it is VERY laggy on mavericks. I also don't like them at they sell this as a touch screen. But you have to pay for the touch drivers on Mac (free on windows). Overall good, but I currently would not recommend if you are a Mac user.
Summary: Bought this as a replacement for my home automation system. One USB cable connection , load up the drivers and you are good to go. No wad of cables or wall warts to deal with. Bright display and great touch screen.
Summary: I got it because the display on my laptop died. I usually use a docking station with separate 21" display but needed something so I could use my computer when away from home. This little screen works fine, is compact when folded up so it's easy to carry, and gets the job done, so that gets the stars. But the size is very small and the scrolling needed to see around the screen is a bit of a pain so no points there.
Summary: I read some less than stellar reviews but needed a small touch screen for work. This thing works just fine. You have to install the drivers sure, but after that it's pretty easy to get it going and if you calibrate it it's quite accurate. Good product.
