Hello,I purchased this device to be able to use a second monitor on my Macbook Air. I installed the driver exactly how the directions specify. The monitor works for about 10 minutes then freezes up and the mouse disappear on the screen. For the 10 minutes it does work, when I attempt to remote into my work PC, I cannot. Magically, when I disconnect the device, I can remote into my work PC with no issues.It is one thing to have a faulty product, but I have emailed this company 3 times in the past two weeks, and have not received a response. I am disappointed in the product and hope that no one else makes the same mistake I did.

It does not work!

Seems to work fine with no problems. Using it to add 4th monitor to docked Lenovo Thinkpad, haven't tried anything graphically intensive like gaming, etc.

It makes my monitor lag just a bit. If you need your computer to be pinpoint accurate this will be a problem but for me it is on my third monitor so it's not a big deal. I don't love that but it isn't ground breaking.

Fits perfectly and serves the purpose. Shipping was quick

It works perfectly!!!
