The micro cleaning cloth cleaned the screen well and is useful if you haven't already got a cloth for cleaning LCD screens.
Application of the cover is fairly straightforward. There are two peel-off masks, the order in which they are to be removed is clearly labelled. The labels are also useful for removing the masks. The sticker on the outer layer blocks the view slightly as you're aligning the cover, but it's not a great problem, although mine is slightly wonky. The fit is almost perfect: the height is a little short and the width is just right.
The first mask is peeled partly off to reveal the sticky side of the cover. This is applied to the screen, and the backing removed gradually as you apply the cover. The instructions refer to a "provided installation card" that helps with perfect application of the cover, but this was missing from my pack. I used a cork coaster instead, which worked very well. The instructions don't say to then peel off the outer layer, but this is obvious from the label, because it says on it to peel it off after application.
In summary, this sort of thing is always going to be tricky to apply unless you're particularly dextrous. Given that, it's not difficult to apply this one without air bubbles and the cleaning cloth is a good addition. Not many other similar products include one as far as I can tell.
