Strong nerves when applying required!

For over an hour I have now tried this protective film (s) without bubbles, but applying especially without dust particles or hairs of my cats, the Kindle Fire HD. Unsuccessful! Both supplied films never made it to the display without cat hair or speck of dust, and I am completely unnerved.
In recent years I have applied many screen protectors for mobile phones, cameras, tablets and the Kindle, but as a botch I've never had.
Sorry folks, simple application ?! But not with animals in the house, lose your hair.
And it is not entirely clear also. The picture is much sharper without foil. Too bad that you can not return, used since. I do not keep them going in the long term namely. One that I have used for our men Andren Kindle, is already in your shopping cart. 11 euros wasted, unfortunately ...
