Excellent privacy.  I saw one on a co-worker's laptop and privacy-envy compelled me to get my own.

Installation:
 - Pretty straight-forward.  You simply apply either plastic boundary tabs that hold the screen in or you can apply the sticky-tabs (double-sided tape strips included in the package) to the edges of your display screen and then stick the privacy screen against it.  I went with the double-sided strips and although their outline is visible on the boundaries of the screen, it's not disruptive to your viewing.

Pros:
 - The "wow" factor is high.  When you see the screen from outside the viewable angle, the bright gold glare is striking.
 - The glare is not only striking but it is also effective.  You really can't see anything when you're outside the viewable angle and the ambient light is bright enough to give a light source to reflect.
 - When the ambient light is not high enough to create the glare, you still get substantial privacy benefits by darkening the screen as you would expect in a standard, grey/black privacy screen.
 - Color fidelity through the screen is still good albeit you lose ~20% brightness in the throughput.

Cons:
 - Expensive.
 - Lowers brightness of the screen noticeably.  You'll want to do this on a work/productivity machine -- not a machine you're doing graphic design or video editing.  The affect on the brightness would be too disruptive when color/luminosity are crucial.
 - There's a semi-circle cut-out along one of the long-axis borders that gives you a finger-hold to pull the screen off.  It's roughly 1 inch long and 1/4 inch high.  I oriented my screen protector so it's in the upper right-hand corner.  The cut-out area is (naturally) brighter than the rest of the screen and the cut-out is really about 3x bigger than it needs to be to be functional.  Given that I've now got an odd, bright-patch on my screen, smaller is better.
