      Works like a charm, all the media buttons and all. Only flaw, the auth key isn't a copyable text so you have to copy it by hand and it's a bit long. Other than that, it's just right.

      Better than Synergy in that you can drag and drop files between computers. But... It's Windows only. So now other ecosystems allowed.

      Not cross-platform. Useless to me.

      Buggy installation. "Link" button does not work half the time. Would not connect even with correct code and computer name, on the same network.

      It's very reliable, and the double tap to switch screens is great. Clipboard sharing works well too. The little window to show status helps when you have multiple monitors.

      While the description is a little vague, they seem to imply that your keyboard/mouse input is sent to another PC when you move your mouse into a tiny window on either PC.
