The filter works but has many disadvantages. Clarity is not very good with the filter. You need to increase the brightness. Sensory sensitivity is impaired. Eventually the product sticks to the screen but is not uniform. If you use the iPad in an area where it's glare, you can see where the filter sticks to the screen and where it doesn't, and even where it sticks, it's not smooth, which can irritate your eyes. Zagg has a great iPhone privacy screen, they only have an iPad privacy screen option.
