Ease of Use

This product seems to work fine. The only thing I don't care for is the keyboard and mouse reinstall every time you switch between computers. So there is a delay.

-Kevin quote

I am using this on my new Dell, old Dell, Linux and my G4 Apple and the TK-409 has simply made my life so much easier because I need all 4 computers frequently. It didn't first work for my old Dell and my Linux box but that's because a USB keyboard and mouse was never connected to those boxes, so they expected a PS/2 key/mouse, these are old machines. I plugged in the USB keyboard and mouse and booted the machines (one at a time) so they can recognize and install the USB driver for the keyboard and mouse and then I plugged the TK409 back in and everything was fine.

Works great

on 3/5/2007

The switch was easy to set up and use. There is a 1-2 second delay when switching between devices, but that is minor compared to being able to use the same keyboard, mouse AND speakers on 4 separate machines.

High Res Video suffered

on 9/26/2007

I like this and use it every day, but at the highest video resolution for a 24" monitor it is wavy. In three months have had to "reboot" the device.
