Not compatible with my external Monitor and bad Technical support
The basics work fine; keyboard, mouse, speakers
But I have not been able to get the dock to support my monitor. I installed the new drivers from the Kensington web site which seem to work termporarily. However, upon reboot my Dell XPS laptop (running Vista) does not recognize the VGA driver.
I called Kensington for support on this issue. I got the worse support I have received in my life. Support did nothing to diagnos the problem. They claimed it was a Microsoft or Dell issue and that I should call them.

Usless with New VISTA Computers
I spent several hours attempting to get the video form my new Toshiba Laptop- new HP display along with the normal geek stuff- i.e. PDA phone, HP printer, Scanner, sound system - mouse and key board. In the end tossed the Expansion Dock in the heap of older out dated computer stuff- in the end used a powered seven USB hub and ended up with (4)plugs to laptop- 1. Power, 2. Video 3. Sound cable to HP display and 4. The USB Hub.
I feel the conflicts are a result of the Expansion Dock attempting to work with the new VISTA operating System. Just a paint to get the things to play together upon shut down to re- boot.

In the end a Toshiba laptop owner might have to wait for Toshiba to get its Tower Port System a little better engineered- from most reviews it has a way to go- I have not tried it - wasted far too much on hardware and some degree software that does not work as stated.

Looked like a nice docking station but is not compatable

Easy to use, and an unexpected benefit or two
This is the sort of product that should be a no-brainer, but there were a couple of unintended benefits from getting it. Since my laptop has replaced the tower, the level and angle of the keyboard had taken some getting used to, and the dock raised the angle enough to make typing much more convenient. Also, the airflow under the laptop has increased, keeping it a little cooler. The software is simple to understand and easy to install. Definitely a worthwhile purchase.

bought on sale, good value for $
I bought this expansion dock on sale for $99.00, and I am happy with the value for the money. When I plug my laptop into the dock, my printer and monitor are instantly available. (The dock I had before was worthless; I had to reboot my printer every time I reconnected to the dock.) Moreover, I've noticed no lag time in the connectivity. The only weird thing I've noticed is that I seem to have to readjust the resolution on my monitor each time I reconnect to the dock. There must be a way to get around this, but I haven't discovered it yet. There are expansion docks that are much more expensive, but this one works really well for my use.
