I've been using the screen filter for several months, and every time I ask my peers in lectures to test whether the filter actually makes it harder for them look at what I'm doing, they are able to tell me exactly what I am doing at that moment. This is done without them having to turn their face towards my screen; all it took for them was to just shift their eyes and my screen was completely vulnerable. I usually have my screen light on low setting, so again, I tried to make it as hard as possible for them to look at my screen. I DO NOT recommend this product.
Product installs easily and works as described. Travel extensively for work and this is a great privacy filter screen product. Glad to see 3M quality in the Apple store.
It ships with 12 attachment adhesive strips, and this option is an easy install. But, the instructions that are in the the inbox material also include instructions for privacy slide mounting adhesive tab strips as well. Unfortunately this is not part of the in box whatsoever. Found myself thinking I was missing part of the product. From there, I took another look at the packaging. Unfortunately the packaging doesn't really tell you exactly what is in the box, other than "4 ITEMS".
For $34.95, I'd think you could include both installation product options for the customer.
