Size: 14.1" WColor: Black
I've owned this product for about a month now and purchased it because I was frustrated with seatmates on airplanes looking at my notebook screen for the whole flight, trying to figure out what I was doing. This screen works wonders in deterring others from taking glances at my private information. In fact, most people think I'm crazy, typing away on a computer with a blank screen, or so they think.

There are some disadvantages with this screen though. Your seatmate directly next to you will be able to see through the filter to your screen partially, because they are within the viewing angle of the screen with the filter on. But move over any farther and the screen is not visible, nor is it visible across the aisle (if sitting in an aisle seat). About the only other place that it is visible is if someone is standing directly above you, one row back. Turning down the brightness of your screen also helps immensely in blocking people from viewing your screen through the filter at any angle.

(Please note, having this filter installed screens out about half of the light coming out of the screen. If you have poor eyesight with dim lighting and have trouble with computer screens, this product may not be for you.)

Additionally, the clear plastic tabs included with the filter adheres to the plastic border around the notebook LCD screen to keep the filter in place. It works, but blocks about a 1/8" of the screen at 6 points, especially noticeable around the bottom of the screen where the start bar is located.

You'll also notice a large "3M PF14.1W" printed in the top right hand corner of the filter. It's used to help in determining whether the filter is facing the right direction, but it's quite distracting at times.

I'm a consultant who travels weekly. Lots of time on flights makes a privacy filter important to me. Being something of a perfectionist and the fact that I look through it for hours each week, I ordered both the ViewGuard and the 3M filters to compare them. I kept the 3M and returned the ViewGuard. Why?

The image clarity of the 3M filter was significantly better (note that I work with small fonts, spreadsheets, etc. and wear glasses) Yes, ViewGuard, I removed the protective film before making the comparison! Two things bugged me about the ViewGuard: (1) its polarization cuts run diagonally (the 3M run vertically), which is distracting, and (2) the image through the ViewGuard is a tiny bit blurry/hazy compared to the 3M. 3M seems to have a more clear film that they use. A colleague of mine did the same side-by-side and agreed with me.

Both products do what they claim, and both fit my notebook well, although I also prefer the optional vertical mounting strips that come with the 3M product (both come with mounting 'dots', but 3M supplies an alternate mounting mechanism as well).

Let's face it: $50 for a piece of plastic seems expensive, but there's no alternative if you want to work on client (or your own financial) information on a plane. Thanks, 3M, for making a quality product. (And no, I don't work for 3M!)

Size: 17.0" Widescreen (16:10 aspect ratio)Color: Gold
I bought the Gold privacy screen for my new Mac Pro 15.5 Laptop. It works great! Fellow workers complain because they can't see my laptop screen unless they get directly behind me. It works especially well with window light hitting it. If fellow workers do stand directly behind me, I just spin around and they back off. I reordered the one for a 17" Mac Pro as it fits better than the one 3M recommends for the 15.5". The 3M recommended screen fits only over the viewing area and leaves about a 1" border to the edge of the screen and is held on with cheesy plastic tabs that glue on the screen. It looks bad and in two weeks the cheesy plastic mounting tabs fell off. You will have much difficulty cleaning the laptop screen with the cheesy plastic tabs glued in place. The Gold Screen for the 17" Mac Pro fits over the entire screen of the 15.5" Mac Pro and is right to the edge of the entire screen. It just leans up against the screen as it leans back. It is a glove fit and is well worth the difference. It lays down flat when I close the screen and travels well. Don't buy the Gray Screen Filter, the Gold is 500% better! The Gray was a costly mistake. Cheaper isn't always the answer. Also, I bought directly from 3M and paid way too much one the first round. (sales Tax, shipping, and a higher price) This time Amazon was my source. (3M(tm) GPF17.0W Widescreen Gold Notebook Privacy Filter) Roger

Size: 15.6" Widescreen (16:9 aspect ratio)Color: Gold Verified Purchase
I wanted a screen that would provide glare reduction, and thought that added privacy would be nice to have as well. However, this filter is a big (and expensive) disappointment.

First, the one positive note -- the privacy filter works fairly well, as people seated to the side of the screen will not be able to see what is on your screen. However, the filter does not sit flush against the screen, so the image the user sees is a bit warped. It's also going to add a lot of glare / reflection to your screen.

Second, the glare reduction -- this is a joke! There is noticeably more glare on the screen when this filter is attached. I see my own reflection about as well as looking in a mirror... except worse (because of the non-flat fit, the image is warped).

Additionally, the screen is quite a bit darker when the filter is attached.

Overall, the screen may provide some privacy protection, so if that is all you need, this could work... however, you will have to learn to deal with increased glare, a darker screen, and the warped distracting glare / reflection.
