Shipping was fast as usual. I cleaned the display well and put the folio on. A piece of plastic is already delivered in the Packet That makes the positioning of the portfolio without air bubbles easier.
I succeeded in doing the whole thing without a single air bubble on my first try. So Perfect.
So: The way the stylus feels while writing has much improved now. I always thought did writing with the stylus on glass was a bit slippery. Now with the folio, it feels a bit grippier and I can write faster.
The screen protector has no negative effect on functioning or Stylus Touch Interaction.
Excellent product. 5 Stars.
