Display is muddy

On my tablet XORO PAD 9718DR a protective film was applied in the supply already, which had now somewhat worn. Because I feel to be quite disturbing reflections, I have decided for this 'anti-reflective' screen protector. Similar, slightly frosted protectors I feel, for example, very pleasant on smartphones.
The XORO PAD has otherwise a very crisp display (though in my opinion a bit too dark) due to the 'Retina' displays. The original film caused unlike the unprotected display glass quite fine color Krisseln that was not disturbing if you do not watch out less than 10 centimeters on the screen.
The film offered here leads to an even stronger color Krisseln that still bothers clearly noticeable even at normal viewing distance. Worse is the 'muddying' the display content. The overall presentation looks completely out of focus. Reading longer texts is very exhausting. For photos or images without sharp edges of the effect is not so much in evidence. Especially with dark images you can see that the anti-reflection effect works quite well. Since the device is but no digital photo frame, but a tablet, I can give the protective film is not a good rating. The blur caused is so disturbing that I am seriously considering, (probably not antireflective then) to take this film to the delivery of a new slide down.
