Good smooth shifting. It's easy to set up, although there really aren't any instructions other than what you can get online, which can be tricky if your monitors aren't connected. Note that if you are using a shared USB bus (mouse, kb) you MUST connect USB cables (rounded) to your devices, otherwise this bus will not activate. the buttons are pretty weird (mixed yellow and red) and my monitors change the switch position every now and then. I haven't figured it out yet, but it happens.
