Bought this for my XPS 1210 laptop, but was very disappointed as the fitting system (basically small strips of double-sided tape) is incredibly difficult to fit neatly and tape is visible. Expected something more classy at the price. Ripped it off after 5 minutes! Makes your laptop look rubbish to. Absolutely avoid unless you really really really need to cut down the angle of view for privacy. Just about the worst product I have ever bought......
Pros:Does restrict the angle of view.
Cons:Very poor value consider what you get is a bit of clear plastic and some adhesive tape.
Fitting is incredibly fiddly.
Looks cheap and nasty.
Only marginally improves visibility of a Truelife (i.e. very shiny!) screen outside, despite claiming to be anti glare.
