Review on TeamGee Portable Monitor Display Extender 12", Built In Speakers, Lightweight by Nicholas Ortiz

Attaches securely to your laptop. If you have an older laptop with only a C-port it will take a little longer to figure out how to set up both screens properly, but they include all the cables you could possibly need. In this case, it is best to use a concentrator to avoid overheating. This will add weight to your laptop screen, so make sure you have proper support. The 13-inch screen comes without a stand.
